Charging Your Battery Safely
Generally speaking, the best way to maintain the battery is to charge it periodically throughout the day instead of allowing it to completely discharge and charge fully to 100%.
- Don't leave your device in hot areas, especially if it's charging. That may cause overheating. Ambient temperatures can significantly affect batteries.
- If your tablet is charging or you are using functions that cause it to heat up a lot, make sure you are using it in a ventilated place (which means taking it out of its case, if you have one). Do not allow the tablet to sit and charge after the indicator states 100%
- Surprisingly, charging your battery once it hits 50 percent may be a better alternative. Li-ion batteries don't suffer from memory issues like older batteries, however they can be damaged by low voltage.
How to Save Battery Life
Your tablet uses a lithium battery and as such, does not have a 'memory', meaning you can charge it from any level. In other words, you don't have to fully discharge the battery and you don't have to charge it all the way to 100 percent.
In fact, these types of batteries which are also used in all smartphones, 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.
Here are some tips to get the most from the battery…it's better to manually set the brightness to a level that is low but comfortable, and only 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 consumers of battery power. You can quickly access the brightness control by swiping your finger all the way down from the top edge of the display. Adjust the brightness bar accordingly.
Close apps that are open and not being used to avoid using battery resources running in the background. Tap the Square icon in the lower Task Bar. Swipe away the open apps individually or tap X.
You can set your tablet to Airplane mode (Settings > Wireless & Networks > More) when you're asleep or use sleep or blocking modes to set up limits for what your tablet does during certain times of the day, whether that's while you're asleep, at work or in a meeting.
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.
Data Intelligent Sleep – The device will turn off mobile data when the screen is off to save significant power. Go to Settings > Battery Saver> turn on Data Intelligent Sleep.
Turn on Power Save mode when your battery is down to 25% to get you through the day if necessary.
NOTE: You can switch the Battery Saver feature to ON and activate all battery saving features.
