Not Recommended in general Battery Charging has various stages These stages are regulated and controlled by the the charging circuit in charger/ in device by firmware files to switch to various stages. Battery capacity is very much integral to this. By replacing with a battery of higher capacity (or extended battery unless OEM approved) charging may ...

First of all, relax. You didn't break it. Absolute worst case scenario is that your battery is completely dead. If you want to do this the easy way, you can always unclip the back of the Nexus 7(just slide a guitar pick in between the screen-half and the rear-half), unplug the battery (carefully) and either find a way to charge it (put it in another ...

Looking at your issue related to battery and charging (which may not be the sole cause- I am not familiar with Nexus devices) Since you barely used it for an year, it would not have been charged either and the battery could have discharged to very low levels. Li Ion batteries have a protection circuit that kicks in when the discharge falls below a certain ...

Li Ion battery discharge is not strictly linear, (unlike a capacitor ). This ensures available power is utilised till the end of battery charge But it is fairly linear, more so at lower loads as can be seen from this figure, where C-rate or charge rate is the discharge/ charge rate Assuming your app is not a heavy power hog, it is reasonable to ...

well, to be honest if you are rooted, you should install ampre, and measure if you give your phone enough juice. if you drain battery faster than charge, even if screen is off, or if you have good charger and quality cable (good charger means like 1.5Amps and higher) you have broken USB port. its very common, and it makes impression of super slow charging or ...

So, 5 minutes of activity consumed 11% of my battery You are mistaken in saying this, don't forget that the phone is on all the time , so that too consumes power. But yes, 1.6% is a little on the higher side, but not too much IMO, considering that you have so many apps/services running Looking at this, wake locks are reasonably under control Deep ...

Heat is the worst enemy of batteries and your battery being two years old would have suffered damage by "baking" it in the truck for two days Batteries tend to self discharge , higher the temperature, more the discharge As a result, the battery voltage could have fallen to a very low level, wherein a protection circuit kicks in and prevents further ...

There's a fairly good chance you overheated a component in the device. Most likely a charging component or someone. There isn't much you can do besides going to a phone/tablet repair shop. But that could cost more than the tablet itself.

It could be a bad calibration of the battery. Charge your phone to 100% and then use it as normal, without charging. Eventually you'll hit 0% and your phone will turn itself off. Then without turning it back on, charge it until 100%. That can often reset the calibration. Also take note of how long your battery is lasting. If you're not a heavy user you ...

Li Ion or Li Po batteries don't die suddenly - their performance degrades in terms of : a) Short Term: Ability to hold charge and deliver expected performance b) Long Term:: Deliver upto 80% capacity upon being charged / discharged over a period of time (in other words life of battery). The battery is considered to be technically dead if it delivers less ...
