Re: battery drains so fast

What do your battery stats indicate at the end of the day? Quite possibly, Android System or similar will be high, as the new OS settles in.

A Cache Partition wipe may also be helpful.

Welcome as a new member.

It may be that the update and the battery problem are no more than coincidental. Have you considered a new battery?

Re: battery drains so fast

Welcome to Android Central! I agree, the battery might be failing. Does this happen with a new or different battery?

It would help to see some battery stats. Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:

1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).

Re: battery drains so fast

That doesn't include all of the screenshots I had suggested--can you show those? Also, why is there a slight increase in the battery level early on? Did you charge up at one point? Make sure you show us the stats after discharging from 100% to around 20-30%, without charging in between.

Ok, then use it down to about 40%. What about my other questions?

Re: battery drains so fast

Great suggestions. Also, there are processes running that can be disabled. Knowing those can help increase battery life. I don't use Samsung, but usually these processes are tied to the bloatware or unnecessary apps.

Re: battery drains so fast

Does that account for only about 2 hours? How long was the screen on for? Looks like half of that or less. That is pretty lousy.

Try calibrating the battery monitor software. Charge to 100%, then use it until it shuts off. Charge back up to 100%, and repeat this cycle about 3 times. See if things get back to normal.

Follow B. Diddy's method as described above....that does not require root. It's simply a way of charging which will calibrate the battery.

Welcome to Android Central! I would suggest creating a new thread for your device, since it's different from the one mentioned here, and there may be a different reason for your issue. Put it in this forum: Dell Venue 8 7000 Series - Android Forums at AndroidCentral.com
