Can not recalibrate battery

Im trying to recalibrate my batter because of terrible battery life. After letting it die and charging it while its on I had no issues getting it to 100%. I powered down the phone to charge it while it was off and it seems like its hanging at the last percent and wont go to 100. I have had it plugged in for a few hours now and its still showing the same charge but wont fill up the last little bit of the meter. Anyone have any ideas? Im really thinking about tossing the battery and getting a new one. It seems like i got a bad one. no matter what I do i can only get about 12 hours of light use. I work 10-12 hour days so I have to constantly worry about my phone dying everyday I work.

I had the same issues. Tried every battery trick I found on the forums, but nothing worked. I went to ATT, they sent me a new battery and it everything's good now
So try talking to ATT and getting a stock OEM battery before you buy one

I picked this up and it gives a lot of peace of mind: http://www.amazon.com/gp/product/B004206TQ8/ref=oss_product

Dngen. Are you getting greater battery life now that your using a different battery? I'm convinced the first batch of batteries and phones were bad.

At first I thought it was the phones that vary in battery life.
My first captivate had really good battery life. But it bricked after I tried to do the JH7 update. So I got the phone exchanged, but they used my original battery in the new captivate. For some reason my phone was draining really fast compared to my old captivate, and this was weird because both used the same battery.
This was really annoying me cause I loved this phone, but the poor battery life was ruining it for me. So I went to an AT&T store and told them how bad my battery life was. They shipped an OEM battery for free and I've found a new battery to significantly work better than the old one

Hmmm. I just got a replacement phone and everything works better...GPS ect... but the battery was the same as it is now.....10-12 hours. I've been thinking about getting another battery but I don't know if that will fix the problem. I guess I will try to anyway.

How long have you had your replacement phone? I know my battery life got better after a few days with my original captivate

I got my replacement phone about a week ago...I've been trying to drain and charge to make sure the system is getting a good read....I've had the battery since launch...the only time I got great battery life was when I used unhelpfuls undervolting and the first time I flashed jh7. I have only flashed one rom on my new phone. It just bothers me that it drains 5-6% an hour in idle. I don't have any Widgets and the only thing that is updating is email once an hour

I think I might have caught a break....on my fourth day of charging and draining and I'm at 16 hrs with. 27% left. I guess ill continue with the whole charge and drain thing for the next couple of days.
Sent from my SAMSUNG-SGH-I897 using XDA App

I somehow doubled my battery life. After draining and charging the last few days I managed to go from 12 hrs to 24 hrs of battery life while using it the same amount as before. I have had had my phone since launch and battery life sucked. I don't know it its because I got a refurbished phone that did it or what. I flashed my old phone almost every day for awhile. Even when I didn't flash I couldn't get it to last.

Have you guys seen this thread?
http://forum.xda-developers.com/showthread.php?t=806211

Good stuff, thanks

I've seen it and read most of the battery threads out there. I've come to the conclusion that: 1. There's a bad batch of phones out there that cause battery drain issues or 2. Since most of us ATT android users are new were unaware of the proper procedure to flash roms. I believe the second to be more true since most of the batterry drain issues happen due to flashing new roms according to most of the threads I've read. I would like to see the percentage of people out there who are still running there cappys stock with never Modding or flashing to see what type of battery life they are getting.

Before rooting, sideloading and flashing unhelpful kernel I was getting the same battery life, 10-15 hours depending on use. The only thing unhelpful seemed to help with was my idle usage, about 1%/hour. I still need to tinker with the kernel and try wiping my bat stats. My phone reports the battery is at 5% but when I shut it off and plug it in it's more like 30% lol
Sent from my SAMSUNG-SGH-I897 using XDA App

I had the same issue. Charge until full. Turn off and charge full... turn on and repeat. Erase battery stats via CW. The key is to let it die. Do not charge your battery until it dies....once it died I plugged it in and turned it on. If its at 1% then just let it charge completely. If its at 30% then you need to unplug and let it die again. Keep doing this until its at 1% when u plug it in. If you have to do the latter you have to start the process over again and erase stats and drain and fill the batterry. From here on out anytime you flash a rom make sure your phone is at 100%. Always let the phone die before charginging it the first time. I think the android system has to get a read of the batterry.
I think at some point along the way I charged my phone when it was at 30% after a flash so anytime after when my battery was dying I still really had 30% battery left but android was telling me my phone had no juice.. let me know if this works for you....

How are you doing on battery?

So I'm wondering how you guys are holding up with the battery. Can you last all day?
If not, do you have a spare battery or anything? Thanks.

Mine lasts about 16 hours on moderate use. I have Set CPU to be around 700mhz while screen off. That seems to help and the fact that im on the optimized TPC ROM makes it all better.

Figure 20 hours till the phone starts nagging. I do a lot of texting and emails throughout the day. Phone goes off charger at 6am and is back on charger by 11:30pm. Display brightness auto adjusts a lot too since I work outside a lot.

Mine seems to last the day. Well night in my case. But I just plug it in when I goto sleep. I ordered an extra stock battery from ebay for 6.98 shipped

Wait till you guys get ginger bread, they improved idle power drastically. I'm unplugged 15 hours right now and still at 71% battery on my nexus. Granted this was over night, but it was never this good before. Idle current stays around 10mA which is excellent.

My idle, on my inspire with TPC's froyo Rom, is anywhere from 1mA to 5mA with the occasional spike to 30mA.

Honestly you can ask, but in all its relative to: amount of use/what you are doing (ie:games or texting)/ROM/kernel/radio/health of the battery. Expect anywhere from 8hours-48hours depending on your usage. Though I have never played angry bird for 8hours straight....

That is very impressive. I need to try some more ROMs out there. The stock inspire here is at 24mA idle pretty regularly which isn't bad but not great.

I get about 12 hours of battery life with heavy use and 20 hours of moderate use. Usually I have the display on for three hours and sending about 100 texts a day about an hour calling with email coming in all day.

This post gives me hope. I am so sick of my iPhone 4, but have been scared the battery will suck on the Inspire. Anyone have/had an i4 and can compare with their Inspire?

IPhone 4 will definitely get better battery life than any android phone. But not too bad and totally worth it.

I pulled my phone off the charger at 8am, it's now just after 10pm and I have 46% remaining. I was browsing on wifi and playing words with friends for about two hours this afternoon, made a few calls, sent a few messages and regularly checked emails.
Battery life on my Inspire hasn't been as good as the Streak, but definitely better than my Captivate. I'm using SetCPU 1024 max/245 min ondemand for my main profile and 245 max 245 min ondemand for screen off.

The key indicator for me is screen-on time. Taking the phone of the charger at ~8am, by about 10pm, with gps off all day, and WiFi on only as needed (~1hr total), I'm at around ~15-20% battery remaining, with the total screen-on time being ~4.5 hrs for that day.
Most of that screen time is playing angry birds, so I'm sure that factors in somehow, as the screen doesn't seem to drain as much battery doing other stuff, as it does playing a processor-intensive activity like a game.

That's good, 4.5 hours of screen on time is a lot.

How is the update going for everyone

My battery going died quicker
Sent from my ADR6400L using XDA App

haven't noticed a battery drain, but its only been overnight.
Update went fine, like the data widget.
Hopefully fixes my wife's rebooting issues.

I haven't had a reboot neither bit in 30 minutes and at 92 percent on extended battery
Sent from my ADR6400L using XDA App

my battery is worse...using extended.
I'm not happy

?
What a joke.
I seen no difference with the update, except the addition of more bloatware, and the removal of free WIFI hot-spot.
My battery appears to drain quicker. But no re-boot yet.
If you don't need it, don't update until the free hot-spot is blocked.

So far so good my battery is much better and the phone is a little snappier but I am missing the tabbed app drawer anyone have it?

I have not updated yet, and am leery. Is it true that it kills your Skype Video Calling? Also, re: battery life, are those who have updated notiving better performance?
Sent from my Xoom using XDA App

Has anybody tried to wipe their battery stats...? Could help.

Battery is unbelievable actually. In a good way. 8 hrs off charger. 81% light use. Couple calls and several texts. Seems snappier too. No reboots.
Sent from my SCH-I800 using XDA App

My batery is also doing much better. Off charger since last night after the update, I am at 62% with light use today on wifi as I have been home. It idles at half or less power drain as before.

I can't lie... Battery life has been much better, and by now I would have had at least 3-4 reboots, and I've had none. Now just get me Gingerbread, and I'll be a happy camper! Oh and I'm noticing no text lag as I type this as well.

Just installed a cm7 theme. Getting better battery life?

Seems weird. But I swear I'm getting a lot better battery life. All the same widgets are running and I'm running a live wallpaper now. Am I just imagining things?
Sent from my Sensation using XDA App

Maybe. Maybe not. Sometimes the compression of the themes can affect battery life. Which theme please? I'd like to try.
Sent from my Sensation using Cyanogenmod

It might be a placebo effect. Just keep using it and perhaps it'll be noticeable.
One thing I noticed is that right out of installing CM7, I thought my battery wasn't being used a lot, but then I noticed the battery meter wasn't draining at all, and so I did a shutdown + battery pull, and then started it up again, and the right battery meter showed up. I've had to do it the first 2 or 3 cycles, but now the battery meter seems to be completely fine now.
The battery life for me is definitely better. I have Wi-Fi on all the time and I made my phone sync to everything basically every hour and so far it lasts me 12-18 before I hit red.

I'll get back to you both later when I'm not busy. Saw that you were both online so wanted to at least reply.

Battery

How much battery do you guys usually get? Recently I've noticed a large drainage of battery and I know phone isn't too good with battery but even this doesn't seem normal. Some of my apps use 1-2% of battery per minute! Is this normal or not?
Sent from my SGH-T769 using xda app-developers app

Oh and my battery never gets to 100%, the phone will tell me it has reached 100% but as soon as I unplug it, the battery is usually at 92-95%, also I use Juice Defender and it seems to help but not much..

generally my phone will last all day, but that is only when i rarely use it. when im using it a lot, for example if im playing games and listening to music, it lasts about half a day. but it all depends on how you use it. if you are using a lot of 3D apps, your battery will drain quickly

Mine lasts all day. I listen to local music and have push email hitting me most of the day. I might have to charge it at night if I use it a lot and I am up past midnight.

I think the Blaze battery is one of the best I've seen. I use my phone lots from 8am till 23:00 and it gets down to about 5%.
That's on Dark Knight ROM.
Sent from my SGH-T769

Odd ive got over a day on my battery with over 4 hours display time on my blaze with erikkm's darkknight rom with moderate use Lithium ion batteries have a memory and when you fully kill the battery it reduces its memory slightly, always always try to charge your phone before 30-20% and dont unplug your phone while its charging that can effect the battery memory as well.
