Help What's wrong with this Core Prime and/or batteries?

[AppleUser]

I have two batteries for the Core Prime. I usually get 3-5 hours of talk time with either battery. One is an OEM Samsung, the other generic. In the past three weeks when either of these batteries are in the phone, they charge to 100% within 30 minutes! But then after removing the USB cord, within minutes, the charge drops to 80% and there will be about 20 minutes talk time. The batteries are 10-24 months old.

Other than buying a new battery, what can be done to troubleshoot and maybe fix? Where to check on which apps are draining?

Hi,

Ah yes, I know this well. My OEM battery started to play this game recently. For me the phone would start to turn off at incrementally higher percentages until it would report charged even after it had just turned off. I think that the overcharging protection circuit had malfunctioned and was reporting charged when it was not. For me going back to my old battery fixed the problem, so I (and the battery manufacturer) suspect battery failure.

In your position, I would try a new battery. Although your batteries are young, OEM batteries can start to fail after six months (cheap cells are used to keep costs down) and if you are regularly burning thorough a battery in 3-5 hours, then 18 months from the original battery is good going. Batteries can only be charged so many times and I guess you charge a lot.

Regards,
Eric.

Okay. Will get a new battery. Thanks. Where does one find the apps which are running and consuming power?

There are two possibilities. The first is the screen that displays the battery consumption graph (settings->system->power saving on my phone). Here you will see a list of the applications that most use your battery. Also, if you have developer options enabled, you can look in the "process stats" section. This will give you more details, but be careful of what you kill in that list since some are system processes and killing them can break things.

However, if you have the screen on a lot, that is the biggest battery drain. The next thing would be if your CPU is constantly in use. You can install CPU spy from the play store to take a look at that. When you are not using the phone the CPU should be in idle state quite a bit of the time.

Check and see what you have running in the background because it's sounds like you have a lot of auto startup apps running. Also if you're in a poor connection location that will make your device processor work harder because it's trying to keep connection with a poor signal if you're on mobile connection in turn will pull down the battery causing your device to working harder to stay connected. If you're on Wi-Fi and you're still having that issue it's because you have a lot in your background running or possible you got 2 bad batteries and they need to be replaced. It's never a good idea to let your phone charge to 100% because the battery has only so many charging Cycles the manufactor designed it to handle. It's best to charge your phone to at least 95% and let the battery run all the way down at least once a month then do a full recharge.
