My Android phone dies at 85% battery life; need a solution

Nov 28, 2018 10:54AM PST

Hello techies;
Off late my Android phone is acting weird. It takes about 45 minutes to an hour to get charged completely and then when I start using it, the charging levels drop down pretty quickly. Once the phone's battery life gets below 85% it dies out completely. Checked the Battery usage and there's a steep curve down after it reaches 85%.

I have already changed the old battery for a new one, but that doesn't seem to be a solution. The problem still persists. After checking a couple of blogs I did wipe out the "cache partition" just hoping the problem would be resolved. But that too didn't stop my phone's addictive nature of being charged 24/7; yes, that's true. I have to keep my phone connected to a charger while at home, to a USB while at work and to the jack while commuting! I am barely able to perform any task or answer a call without keeping my phone charged continuously.

I did check this with a local service center and they seem to have no clue (I know they aren't capable enough)

I am pretty frustrated now! any good techie's out there who can help me out with a solution for this.
I can buy a new phone like tomorrow, but just want to defy myself on getting this current problem sorted.

By the way; I use a Panasonic Eluga i2.

Thanks in advance! Cheers!

If you look at our mainpage cnet.com/forums, you'll see the Android forum you posted in is listed with the OS forums. Why do you think this is an Android issue, not a hardware issue? If it is, going back to factory conditions is the solution.

I think it's a hardware issue. Since it isn't in the battery, it's somewhere else in the phone. Replacing the motherboard is the next step.

Another info! Thought this might help.

Another info! Thought this might help.
At times; when I restart my phone it says "Android is starting: Optimizing app 1 of 51" and this takes nearly 20 minutes to complete.

https://thewirecutter.com/blog/why-your-phone-dies-when-it-claims-to-have-battery-left/ kicks around the issue but in short I bet there are still battery issues. We know that "the estimate on your battery meter isn’t always perfect" but as there are fake batteries out there it may be time for two things.

1. Bite the bullet and do a full factory reset on the phone. Owners push back on this but if they don't I can't be sure if it's just some app eating the battery. In your case I'm going with unlikely.

2. Get a new battery and by another maker. Everyone is running into fake batteries today. They are all over the market now and the signs are just as you wrote.

If these 2 things don't fix it, I'd shop for a new phone.

That tells me the factory reset could help.

Let me give a final try!

I shall check with another new battery on my phone and ensure the problem is solved. If solved will pay for the new one else would get a new phone!
Either way; will keep you posted.

Once again; thanks for your time!

And that new battery better not be

From the same maker or seller.

You also need to fix the Optimizing issue.

that's for sure!

I wouldn't go back to the same maker or seller. Will check out at some other stores.

BTW; what's your suggestion/solution for the optimizing issue; any insights?

The tech in me says "factory reset." But I know folk don't backup so that's why many won't. There are other ideas in the google research I provided you. As a rule I don't duplicate those ideas here.

thanks!

I will backup the data and do a factory reset again.
Shall check the other ideas on the google research forum too.

I missed where you did a factory reset.
Nov 28, 2018 1:44PM PST

I read about a clear cache but that's a partial clearing.

If you read those discussions on the web they seem to slam certain apps as the cause. So here's the story. A client was having issues with a PC or phone (doesn't matter.) So the machine/phone is hosed. We factory reset it and all good but the client comes back. This happens a few times and finally they show us what they are doing. Bingo. Some bad app.

Hey,

I would dig deep into software issues, maybe install a custom rom.
Make sure there isn't a single error that causes crashes on a software level.
When you are 100% sure, you have faulty hardware and should go for another phone.
