With 3g on I get about 8-10% drain, but with 3g off its just about 2%.
Install some app like better battery stats and check which app is draining the battery.

Try if it's working when you plug it to the PC, there have been reports (same issue as yours), but it still worked with the PC. But sry no other solution present AFAIK except warranty.

Hey
If you've lost 20% with your screen on constantly for an hour and a half and played a battery hungry game for 10 mins then I'd say you're getting average battery performance.
That side, you can hardly give it definitive answer Based on the info you've given. My advice is to grab Better Battery Stats from Play Store and run your phone normally for a couple of days.
The big problem with this phone is that it's impossible to put down though

ur mobile coverage is rather bad...
could be d cause.
looks normal to me for continue use.. screen, wifi, etc on almost the entire hour and a half. once the device goes idle/sleep the "awake" bar should not be blue, otherwise if it stays blue that means a app or something is keeping it awake.
I had avast anti virus and it was keeping my phone awake.. So I uninstalled that

Better Battery Stats for the apps and wake_locks and cpu spy for cpu sleeptime mate
You can also disable fast dormancy.

That seems normal to me. I bought a second Samsung battery. Now, I'll never be afraid of running out of juice! It's worth it compared to getting a 4,000mAH battery that makes your slim samsung turn into an obese samsung. :fingers-crossed:

Sola sleep well but battery jump down overnight with 3g data off

Hi. Brothers! I found my sola sleep well last night(no wake up) and with 3g data off but battey drops crazyly. Is it a bug or my battery is out of order??? Thanks!

Seems to be the battery. Such huge drain doesn't happen in deep sleep mode.
Sent from my ST25i using Tapatalk 2
maybe an app you installed is on background using resources while on Sleep... try a factory reset before you blame the battery
I have the same issue. Started using Juice Defender and it really helped my battery. As it is, Sola's battery life is poor, so on 3G its really sad.

I also think that there is a app which drains your battery very much

About battery life

Best app to diagnose the battery

Hi
Just the title says I want a good app to diagnose the battery and tell me what is juicing it.
I'm with a S20 plus 4g with 5h sot at the most
Thanks @Deiota
