Battery going from full to half full

charleslongsr · #1 (**permalink**) 03-31-2011, 06:35 PM

Ok guys, I was having an issue with my battery or atleast I thought it was my battery. I would charge my phone and it would be full. After some usage, nothing major and maybe 30 minutes it would be sitting on half. It hasnt been like this and I have had the phone for almost a year. Well, I have replaced the battery with an extended life battery and it is doing the exact same thing. So now I am thinking that the issue may be in the rom. Just so that im clear, it will appear to be full 90-100 then all of a sudden drop to half full. Any suggestions or should I just call sprint up?

I had a similar issue and everyone thougt I was joking. My phone would go to 80% and stay there. I was getting record battery life. The only problem, that after a reboot, it would be at 30%.

Indeed, it was the Rom. Reflash and replaced.

My problem now is deciding whether the battery is half empty or half full.

If you are charging the phone it should be half full, i think, not sure, lol
I'll thank you, I care.

the phone, o/s, and battery do not agree what 100% & 0% actually are. let fully die, until the phone will stay on less than a minute. then fully charge. (preferably while off, then without unplugging boot into the o/s until it reads full as well)

also if you only ever use the top 50% then it will wear out quicker than the bottom 50 so the bottom will work better than the top.
there are times when my phone will survive a day on less than 5%. that's how I know it's time to calibrate again.

Thank you for your reply. I think its the ROM also, as stated before. I normally let the phone get low before placing the phone on charge, but I started let it run to the point of shutting off. Nothing changed with doing this. My question now is should I just do a hard reset or just flash to a new rom? I have one app that I am really concerned about other than that one app, I could care less about the rest. I just want longer battery life, which is why I replace the old battery. (Besides thinking that it was bad)

I would reflash the rom and wipe the battery stats and I would also try a different kernel.

I'm rooted but all stock (never replaced with any other rom) and this was happening on my original battery so I purchased the seidio 1750 extended battery. At first, my batt life was acceptable and lasted all day then all of a sudden...BAM...50% within just a few hours. I have recalibrated my batt, charged while OFF, killed running apps manually (I don't use task killers) to no avail. I noticed though, Qik and fancy widgets keep popping back up like a bad pimple and the new lookout update added new processes which may be contributing to my bad battery performance. I don't know though, I guess I'll keep killing the processes or I'll unroot, wipe, and start from scratch to see if that takes care of my problem. Regardless, this is unacceptable battery behavior.
