Smartphone batteries don't last forever, and some devices have an almost-embarrassing screen-on time. Those big, luscious AMOLED and LCD screens and taxing apps are an obvious drain on your battery, but there are lots of things you can do behind-the-scenes to make your Android last longer. Let's explore how to increase battery on your smartphone.
How Android batteries work
First, some background: most smartphones have either a lithium-ion battery or a lithium-polymer battery. Both are actually lithium-ion though, and as such, do not have a 'memory', which means you can charge them from any level – you don't have to fully discharge them before charging them up – and you don't have to charge them all the way to 100 percent.
Mobile phones use lithium-ion batteries for energy storage. In this type of battery, lithium metal and lithium ions move in and out of individual electrodes, causing them to physically expand and contract. Unfortunately, these processes are not completely reversible and the batteries lose their charge capacity and voltage as the number of charge and discharge cycles grows.
To make matters worse, the electrolyte (electrically conductive liquid) that connects the electrodes also degrades throughout these cycles. The ability of lithium-ion batteries to store charge depends on the extent of their degradation. This means there is a link between how we handle our devices today and the charge capacity available in the future. Through a few simple steps, users can minimize this degradation and extend their device’s life.
Here are some useful strategies for extending your phone’s battery capacity:
Typical lithium-ion batteries for mobile phones are supposed to retain 80% of their charge capacity after 300-500 charge/discharge cycles. However, batteries rarely produce this level of performance, with charge storage capacity sometimes reduced to 80% levels within only 100 cycles.
Fortunately, we can extend our future battery capacity by limiting how much we discharge our mobile phone batteries. With most battery degradation occurring during deep discharge/charge cycles, it is actually better to limit the battery discharge during any one cycle before charging strategies it happens, our devices do have battery-management systems, which reduce damage from overcharging and shut down automatically if the battery gets too low. Nonetheless, to maximize the battery capacity in the future we should avoid that 0% battery mark altogether, while also keeping those batteries at least partially charged if storing them for a prolonged period of time to avoid deep discharge.
Many of today’s mobile devices have a fast charge option that enables users to supercharge them in minutes rather than hours. This is convenient when we’re in a rush, but should be avoided otherwise. Why? Because charging a battery too quickly reduces its storage capacity. Physically, the shuttling of lithium metal and lithium ions between the electrodes in lithium-ion batteries is a slow process. Therefore, charging at lower rates allows more complete shuttling to occur, which enhances the battery’s charge capacity.
For example, charging a phone in five minutes compared with the standard two hours can reduce the battery capacity for that charge cycle by more than 20% .
The exact range in which lithium-ion batteries can be stored to maintain optimal long-term charge capacity is between 0℃ and 45℃.
Below 0℃, the amount of power available within the battery system is reduced because of a restriction in the movement of lithium metal and lithium ions within the electrodes and through the electrolyte. Above 45℃, the amount of power available is actually enhanced compared with lower temperatures, so you can get a little more “juice” from your battery under hotter conditions. However, at these temperatures the degradation of the battery is also greatly accelerated, so over an extended period of time its ability to store charge will be reduced.
As a result, phones should be kept out of direct sunlight for prolonged periods, especially in summer when surface temperatures can increase to
above 70℃ .
In fact, these types of batteries suffer from low voltage problems, so it's actually better to partially charge them (say, from 20 percent to 90 percent) than to fully charge and fully drain them. Battery care is always open for debate though, so for every accepted tip there will be someone that says it makes no difference. Just find the ones that work for you and you can increase battery on your Android device.
To our chagrin, most flagship devices released in 2016 don't have removable batteries. This looks like it won't change anytime soon. And despite most of them being close to 3,000 mAh they still need to be optimized, especially for Pokémon Go. Take advantage of some of the tips below and really get the most out of your smartphone.
Black wallpaper can increase battery
If your phone has an AMOLED screen (like most Samsung devices), use a dark-colored background. Black wallpaper can increase battery life because AMOLED screens only illuminate the colored pixels. Black pixels are unlit, so the more black pixels you have, or the more darker pixels, the less power is needed to light them up.
Doze Mode
Doze mode has been around since Android Marshmallow, but with Nougat, it's been much improved. Before, Doze would only work when the smartphone has been stationary for a while. But now, it can also work when it's being moved around (in your bag or pocket while you're on the go, for example). The screen just needs to be off to work.
Doze mode essentially just shuts down things you're not using depending on how long it has been since you've touched your phone. Network connection is severed and syncing only happens during specific intervals. When you're away from your phone even longer, more things are stopped, like GPS, Wi-Fi scanning and all syncing.
Turn off Google hotwords
Stop your phone from always listening. Google's OK Google voice searching is a fantastic and often very functional feature. The problem is that it can wreak havoc with your battery. Especially if you don't actually use it or only use it occasionally.
Go into Google settings from your app drawer and tap Voice heading. On the next page, select OK Google detection . In this menu, the best option for battery life would be to untick all the boxes, but if you are a fan of OK Google, just tick the
From the Google app box to ensure your device is only listening when you're in the Google app. Follow along with the video below for the full process.
Don't let your apps fall behind the times
Keep your apps updated. There's a reason developers constantly update apps, and most of the time it's for memory or battery optimization. Keeping your apps updated also means you have the best optimizations available. Likewise, delete old apps you no longer use, because these may be running background processes that chew up RAM and battery life.
Once you've ensured your apps are up-to-date you can go through them individually and check if they're optimized for battery life. This can be done quite quickly. Just go into your
Settings and tap Battery . From there hit the menu button (three dots at the top right of your screen) and go to Battery optimization. From there you can see which apps are optimized and change them. You can only change the non-essential system apps. Watch the video below to see how this is done.
Use the 'Lite' versions of apps
To save battery life, not to mention mobile data, you can take advantage of 'Lite' versions of popular apps. These are stripped down to their essential features and designed to be simpler and more economical than their full counterparts.
Facebook and Messenger both have Lite apps available in the Play Store. Skype also has a Lite app in the Play Store, but it may be unstable as it is technically unreleased. For services like Gmail,
Twitter and Instagram, there is no Lite app available to download. Instead, these three have mobile-friendly websites you can access from your browser using the links above.
Use Greenify
Unlike many Android apps that claim to optimize performance and increase battery life, Greenify actually works. Greenify allows you to put other apps into hibernation when they aren't in use, preventing them from operating in the background.
This frees up system resources and boosts battery performance, but requires a bit of thought. For Greenify to be effective you can't just hibernate every installed app. But since there are a lot of Android apps that perform actions you don't know about, or necessarily want, this is a useful tool.
This can be helpful in many situations. For example, you might use the Amazon app to browse for things to buy, but don't want it to operate in the background or send notifications. There might be other apps on your Android device operating in the background without a good reason. Greenify stops this by sending those apps into hibernation, which reduces their impact on the system, saving battery life while improving performance.
Doze promises to reduce battery drain while your device is not being used.
Don't use adaptive/auto brightness
Don't use display auto-brightness. It may sound useful, but auto-brightness is usually way brighter than you really need. It's better to manually set the brightness to a level that is low but comfortable, and bump it up when necessary. This is one of the best ways to improve your battery life, because the screen is one of the biggest battery suckers.
To ensure your adaptive/auto brightness is off go into the Quick settings in many devices and you should see
Auto with a box above and a checkmark in it. Uncheck this box and your auto will be off. With some devices you might need to go into the Settings then tap Display . From there you should see
Brightness level and in it you'll find the auto settings.
Save battery by using the manual brightness controls.
Turn off vibrate and haptic feedback to save battery
Switch off vibrate. Unless you really need that added awareness, turn off vibration alerts for incoming calls. It actually takes more power to vibrate your phone than it does to ring it. Turn off haptic feedback too (that buzz you get from typing on the keyboard). Sure it feels cool, but it doesn't really add anything to your experience, and it's another battery drainer. Watch the video below to see how you can do this.
Set your 'Do Not Disturb' or 'sleep' schedule
Set sleep times or blocking mode to switch off Wi-Fi and mobile data when you don't need them. If your phone is basically off limits at work, set your device to not ring, vibrate or connect to the internet while you're at work. Many phones have a Do Not Disturb setting for just this purpose.
Likewise, you can set your phone to airplane mode when you're asleep or use sleep or blocking modes to set up limits for what your phone does during certain times of the day, whether that's while you're asleep, at work or in a meeting. Cool apps such as IFTTT let you create rules that can help you save battery life too.
You don't need to be connected 24/7
Turn off GPS, Bluetooth, NFC, Wi-Fi and mobile data whenever you don't need them. Turning off location data, or changing your location settings to use Wi-Fi or 3G data rather than GPS works perfectly well. This will increase battery on your Android device.
Only turn on Bluetooth and NFC as long as you need them (even though they consume very little power), and there's no need to have both Wi-Fi and mobile data turned on at all times, especially if you know exactly when you'll need one or the other.
If you use Wi-Fi a lot though, say at home and at work, then it makes sense to keep set your Wi-Fi to 'Always on during sleep' as this uses less power than to have your Wi-Fi reconnecting every time you wake your phone. Most of these can be found in your Quick settings .
Don't get bogged down by widgets
Ditch widgets you don't need, especially those connected to the internet, such as weather widgets. If you have multiple widgets across several home screens, which are constantly syncing and updating (Twitter, reddit, weather, Gmail and the like), you're not doing your battery any favors. Just hit the apps when you need them.
If you already have a bunch of useless widgets on your device then you just need to do a couple of things and they'll be gone. Long press on a blank space on your home screen. Now drag the widget you don't need into the trash bin at the top or bottom of your screen (it depends on the brand).
Explore the battery saving features on your phone
All ROMs, whether stock Android, OEM UIs such as TouchWiz, or custom ROMs like CyanogenMod, have various settings in the menu to help conserve or optimize battery consumption.
HTC has Extreme Power Saving Mode, Samsung has Ultra Power Saving Mode, Sony has STAMINA mode and so on. Find these various options for your device and ROM and make them work for you.
Even if your phone doesn't have layers of battery saving features like some (or you simply don't want disable so many features), at least make use of the basic battery saver mode.
Battery saver promises to reduce battery drain while your device is not being used.
Don't fall into the auto-sync trap
Turn off auto-syncing for Google accounts. If you don't need every single Google account updated every 15 minutes, just go into Settings and Google account and turn off auto-sync for those apps you don't need constantly updated.
Some apps – like email – let you manually refresh when you launch them, rather than running multiple auto-refreshes throughout the day when you may not need them to. The same goes for Twitter, Reddit and co. Unless you need constant updates or push notifications (like for Facebook or your calendar) just sync when you actually use the app.
