I just bought one of those Anker 2200 mAh batteries since mine has been starting to go. I'm wondering if there is anything I should do before I put it in so the phone can calibrate to a new battery. Something like wiping battery stats, letting it charge to full then discharge completely, or anything else. What do you suggest?
I am on a recent PAC-man CM based rom.
Thanks!

You'll get all sorts of advise when it comes to a new battery. Some people have some really elaborate routines but I really don't think that is necessary. I think you already have a good idea what to do.
Others say that there is no need to wipe data and cache or wipe battery stats. As long as you charge the new battery on the first time it was charge for about 8 - 10 hours even it its 100% already.
I got 2 of those with an anker charger on amazon. I switch between them and my OE Sammy battery (mostly on vacations) with no issues. I just pop them in and go. Sometimes they aren't even 100% since if I know they are going to sit around out of the phone for long its best if they aren't 100% charged.

I bought 2 x aftermarket 1600mah batteries from eBay with a charger to charge them directly.
I don't have high hopes but I figured for £10 I couldn't really go wrong.
So I charged one of the new batteries in the supplied charger overnight and tried it out this morning. At first boot, my Desire HD said the battery was empty and to connect the charger. If I leave it the phone shuts down after 20 seconds. I did connect the charger and and then instantly the phone said the battery was 99% full. After I disconnected the charger the phone has run all day on one of these ebay batteries, with life being comparable to the stock battery.
My question is, is this some kind of software glitch? Or a problem with the charger pergaps? I am using Cyanogenmod 7 (Gingerbread). Anyone else seen this issue?
I'd like the phone to report the correct power level when I swap the battery, so that it doesn't shut down automatically, and can be used when Im away from a charger.
where can i find a 1600mAH official battery??

I have the same issue with what sounds like the same batteries and charger running cm6. The problem isn't there when I use the stock rom. Think it's a cm issue. I don't know of a fix except that sometimes wiping battery stats before booting sorts it out. Good luck and if you find a fix, please post.

Not a fix, just my workaround:
I charge the phone with the unofficial 1600mah battery overnight, and run it all day until it runs out. Then I switch to the official HTC battery, which lasts me all evening.
For example I went to a wedding Saturday, and taking pictures/playing Angry Birds during the boring bits, the two batteries easily lasted the whole day. I don't think the 1600mah battery is any better than stock though. Wouldn't say it's worse mind.
I think the CM7 builds have issues around battery life with WIFI/Bluetooth and Cell standby. From what i can see.
I'll let you know if I find a fix though!
Alright so it's difficult to explain this fully but I'll try. I came across battery calibration information and I went ahead and wiped the stats. I then let it drain, charge full then drain again. Now as it was charging I decided to flash another ROM, done. So that ROM took a while to fully charge but when it did I got 13hrs of battery life out of it. Now when I charge it, pretty much it stays around 50% and wo't bump higher. Literally haven't hit higher after leaving it plugged for more than 3 hours. Anyways I'm about to flash a update of said ROM and use a different kernel that is know to be more stable. But curious if there is hope for my battery? I don't plan on wiping battery stats anymore, after further readings I see it's not worth the trouble.
I was reading around the forum and through all the things about extended batteries and stuff to decide that I was going to buy the Mugen 3200mAh one.
My question is Droidzone has this thing called "EBatt/EBFix=Droidzone's fix for Extended Batteries". Do I need that for my extended battery or will it have no problems with charging? I believe his fix is set for 2400mAh but mine is 3200mAh.
I put in my extended battery and it was at 0% charge, only thing I notices was Battery Widget Widget Pro didn't know how many mAh so I assume neither does the phone (because its not an official HTC battery).
I'm doing what the Mugen User Guide is telling me, which is to charge the phone for 8-12 hours even if it shows full charge for the first 4-5 times.
Correct me if I'm wrong but I'm assuming that the battery will charge but take a longer time to charge but will still show 100% (also will the battery % be completely wrong all the time because the phone doesn't understand the maximum capacity is greater now).
So back to my initial question, do I need to flash a extended battery fix kernel or just calibrating the batteries should work?
As far as extended batterys go, yes you need a kernal which supports it. I'm shopping around for a Yoobao battery and I'm finding out which kernal I need which will support the information for the battery.

Any luck on finding one? So the battery won't charge to full capacity without the appropriate kernel?
With the kernels I've only found droidzone and I don't particular have the time to test all the different kernels on my phone.
I tried doing the full charge without using a different kernel, I will see the results of this soon hopefully.
It should charge to full but you won't see the real capacity.

Mine charges to 54% then jumps 100$. It doesn't seem to be giving me the full amount I expected. It charged more once for an hour or two after I let it get to 99% then switched off and charged again. Then booted and let it hit 99% and repeated the process about 3 times. Then I wiped battery stats. Now I'm letting it relearn the whole battery thing. It's dropping fast right now... But I think a few full charge cycles are required.
No. You do.not need a special kernel. Mugen battery's are made to.be used with nonroot phones.
Sent from my Nexus S using XDA Premium App
I posted this in another forum and the response I got was somewhat weak. Instead of re typing everything I will cut and paste my posts and hopefully you guys can guide me in the right direction!
Here was post 1 -->
I just bought a Rooted Nexus S from ebay. It is running this ROM Nexus S ICS 4.0.4 stock OTA ROM (IMM76D)
Now, I know nothing about android, I'm coming off a series of old turd phones because i'm always breaking them. I'll probably break this one too, but hopefully not for a while.
When I got the phone I put the battery in and turned it on, then charged it overnight. It will only charge to 54% and stay there. I talked to the seller he said it charged normally for him. He said he did a complete wipe and USB wipe before he shipped it.
The battery seems to drain normally (I guess, I have nothing to really compare it to) from 54% but it would be nice to have it charge to the 90% -ish range haha. I allowed the battery to drain to 40% and put it back on charge, it been on charge for almost an hour and will only charge to 41%? Do you guys have any ideas what I can do to fix this? Is this a sign it needs a new battery, or a software glitch? The seller said the battery shouldn't need replacing.
Also in the battery app under setting, Android System is using 28% is that a lot?
My last question is an important one to me haha. Is there anyway to convert the querty keyboard to a T9? I 've gotten used to texting with one hand and T9 makes it so much easier to do so.
Thanks everybody!
Someone recommended I try the battery calibration app So I did!
Post 2
Ok, I ran the Battery Calibration app. I let my phone charge for hours. It would only charge up to 38% this time. However, the percentage was 38% but it was charged to 3810 mV (and would not charge past this point). And full charge is approximately 4200 mV according to the Battery Calibration app. So I assumed that 3810 mV was my current battery's max charge (keep in mind it is a couple months old) and set battery calibration at that point.
This is from the app description --> It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break.
So thats what I'll do. I should mention that even though I ran the battery calibration, the battery percentage has been draining from 38%. In other words, my phone now reads 26% battery charge, but is at 3758 mV.
I'm thinking that when I go to charge it after fully draining the battery, it will hopefully charge close to 100%. It seems as though the percentage is the only thing that is off. Because the mV reading seems accurate.
Here is a screenshot, what do you guys think?
This site won't let me post the screen shot until 8 posts, but I will do that once I get there!
Post # 3
The app says to let the phone fully discharge after calibration. I am now at 15%, but mV is at 3658. Should I recharge when the percentage has dropped lower, or when the mV reaches a low point? Are these phones really this finicky. I'm starting to miss my old 2007 flip phone haha
It's now at 14% and now asking for me to plug it in to charge lol but mV is still way high (3655)
Post #4
update, charge % reached 0 and the phone shut down. Now charging, Current charge is at 0%, 3595 mV. No one has any idea whats up?
Shouldn't mV be near 0 when charge is at 0%, and be near 4000mV when charge is near 100%?
hopefully you guys can help me fix this issue. Otherwise it'll have to go back to 'ol reliable, the 2007, multiple cracked screen, nokia slider lol It's not pretty, but it works!
There is a built in safety feature in our batteries to prevent deep discharges. IIRC, the safe cutoff point is around maybe 34xx mV. I could be off, but its to prevent damage to the battery. Here's more on them
http://batteryuniversity.com/learn/article/is_lithium_ion_the_ideal_battery
As for voltages, a full battery should be around 4100mV. Mine tops out around 4196. I'm not too familiar with all of it though. Most of the stuff I learn is through observation and links others provide.
Thanks for the reply! So are you saying that when the voltage is around 34xx the battery charge % should be close to or around 0%. And when the voltage is near the 4000mV range the charge %tage should be approximately 9x%
Do I have the right idea here?
Its hard to say while its charging. My phone is at 4000mv around 70% so I don't really know exactly how it works. But a full battery should read around the voltages I posted. There's people on here who know more about it, so hopefully they'll chime in.
But yes. When its close to zero, it should be around that range. It will differ from battery to battery.
Ah k thanks! My original problem was that the phone would only charge to 54% and would not go past that point. I'm waiting to see if it will get into the 90 ish % range after running the battery calibration now.
The app itself doesn't actually do anything. The stats will get reset once the charge reaches 90% My girlfriend's phone was the same way. It wouldn't charge past 75%. I let the phone run dead and charged it while it was off and it fixed the problem. If it doesn't go to 90%, try charging while off and just letting it run until it gives the warning to charge, turn it off and let it charge overnight .
Ok. Well I let the phone run dead earlier today as I mentioned in one of the above posts. But I didn't charge it with the phone off. I put it on charge with the phone on, and now it won't charge past 11%
It just seems to be getting worse and worse? It's been going between 10% and 11% and has been at 11% for about 2 hours now. Maybe this time I will drain it again and try charging it with the phone off like you suggested.
This is slightly annoying
All else fails grab another battery. They're dirt cheap on eBay. Just get one from a reputable seller
Ok, so I let the battery drain. then fully charged it with the phone off. When I turned it on, it had 47% charge.
The guy I bought it from said that before I buy a battery I should download an app called rom manager and download a new rom. he thinks its a software bug because he had no problems with the battery when he was running cyanogen mod 9 on it.
I wouldn't mind giving trying this, except I don't even know what a rom is. Is it operating system? I like the way the phone works now, If only I could get it to charge fully.
Thoughts?
Ok, I just did a bunch of reading and downloaded ROM manager premium. Hopefully I get this figured out. Owning one of these phones is a lot of work
lts pretty much a pocket computer. Coming from an older type of phone, a lot of things are going to be different. Gotta start somewhere. Reading up on it and toying around with the phone will help in the long run. Trust me.

Haha, pretty much. I'm slowly starting to learn more. I didn't think there was this much of a learning curve, thats what took me by surprise thats all. I'm a fast learner so I'm not too worried. I didn't have time to play around on it tonight, maybe on the weekend. I found out I could use it without the sim card which is awesome! Because now I can use old faithful while I learn more about android.
Thanks for the help so far though, I'm sure I'll have more questions soon haha
Haha. Yep. You can have tons of fun just using it over wifi!
Do keep in mind, fully dishcharging a lithium ion (li-ion) battery deteriorates the battery even more. We only discharge because older phones use nickel cadmium batteries which need more maintenance to get to their maximum life span and use.
Off topic though.
Battery calibration just wipes your battery stats. You can do this by going into any recovery program eg clockworkmod receovery or team win recovery project. You can wipe the battery stats yourself. If that still doesnt work. Try doing a clean install of your custom rom or kernel. If your not on a custom rom or kernel. Nor your rooted. Try formating the SD card in the Nexus S (or fully wiping the sd card). Than do a factory reset.
Ok, so I finally had some time to learn to flash etc. After backing up, I downloaded and flashed the same rom from SD, I cleared davlik cache and also selected the wipe data and cache option from ROM Manager (I assume that this is what is called a clean install?)
This is the ROM I am using http://forum.xda-developers.com/showthread.php?t=1653713 Slightly customized stock ROM, rooted.
After start up I waited a while and then plugged it into the charger, it only charges to 54% still. Sometimes it creeps up. One thing I noticed is that if I use the phone while it is charging, it actually drains the battery. So it will go from 54% to 52% and slowly drain. Is this an indication of a pooched battery?
Any suggestions? I will order a battery. Where do you guys order your batterries, I read that the oem samsung 1500 is reliable.
Hi everyone,
I've had my Sensation for about 14 months now and for the past month I've been having battery issues. Primarily, it's very quick to lose charge and will lose charge even while charging from the wall. First I bought a replacement battery but was still having the same issues. I've started using Better Battery Stats and Battery Monitor Widget but I don't have anything out of the ordinary running. In fact, not a lot is running at all. BMW has allowed me to see how the charging is going though which has been nice. During this period I have used Elegancia, Bruce's CM10, and am currently on ParanoidAndroid. All experienced the same issues.
Last night, for example, I put the phone on the charger at 16 percent. It charged up to 22 and then started the downward slide to death and I ended up waking up 35 minutes late.
Where do I go from here so I don't have to constantly be paranoid about my battery levels?
Sounds like you might need another battery. In better battery starts did you notice any unusual wake locks? This could drain a battery. But since it looses charge even when charging I'd think it was the battery. I personally was experiencing some battery issues myself finally I broke down and got a mugen 3800mah battery from mugen. It was expensive but really worth it for Me.with really heavy and constant use I get 20 hours out of my battery, with normal use I get two days. I'm also running paranoid Android rom. For me the big battery solved my issues. Only one draw back, it does make your phone thicker. New back included with battery. This didn't bother me much because of the excellent battery life I receive. Now I finally don't. Worry about battery. However it's expensive at about 95 dollars. But I was so fed up with poor battery life it was worth it for me. You have to be careful when buying inexpensive batteries because there are a lot of fakes going around. And the mah is not really what it says it is on the packages. You can test the battery and make sure it is what it's advertised to be. If you don't want to go with that large of a battery you can also try anker extended battery. It's a lot less expensive and is a good battery. I personally needed more juice so I went with the big battery. I know you said you replaced the battery but sometimes the bargain batteries go bad quickly. It makes me suspicious of the battery because it's even dropping while charging. This is strange. If you ruled out any apps or wake locks that might be draining the battery I would buy a good reliable battery. The draining while charging is a red flag. I'd say the battery is going bad. I don't at all regret my purchase of the big battery. It for me, solved my issues. I do Hope this helps and I wish you the best. Hopefully you will get your issue resolved soon.

its either an issue with the battery or the battery reporting.
Only thing you can really try is to charge it up to 100%, wipe battery stats in recovery, then let it empty totally and charge it up again, see how its behaving. There is a chance that its the reporting that is off.
otherwise this looks like the battery is on its way out im afraid

Argh. I hope it's not the replacement battery too. I got a replacement HTC battery. The problem I'm having getting anything useful from Better Battery Stats is that rarely am I off the charger. In the settings it says I can log while charging but it may mess up the stats so I've shied away from doing that. I'm not against getting a bigger, better battery but I would hate to do that and have it actually be something else hardware-wise where I would need to get rid of my phone.

I'll give this a try if I can get it back up to 100%. Is the reporting in Recovery always correct? The battery never has issues charging while it's in Recovery mode. If that's the case then I'll charge it to 100% in recovery and then wipe and start fresh.
Thanks
I don't think it's the battery. This phones have errors in battery readings. I feel your pain man. Mine is from T-Mobile (Sensation 4G) and it discharges if I use it even at lowest brightness when it's charging too.
If I reboot, I get the battery boost. I have tried EVERYTHING I read here and nothing worked. I even have 4 batteries. All of them in good condition.
I even tried three times discharging it fully and without turning it on, charge it in the night and when I wake up 7-8 hours later, it's still charging. I tried wiping stats, changing ROMs, changing the usb cable and the charger. Everything... I believe it's a hardware issue. (Thank HTC for that) I'm not buying another HTC when I have to upgrade.

Interesting...so if you were to charge the phone in recoery how long do you think it would take to get to 100%?
I would definitely do what you said, charge in recovery then wipe battery stats and go from there.
If you're interested in having something to compare to, it takes my phone about 3 hours to charge to 100% (by the way I'm using an Anker extended capacity battery), with a peak current usually around 800 - 900 mA. Fully charged I have somewhere around 4100 mV. If you haven't already, I'd suggest adding a Battery Monitor widget with mA, mV, and % available being displayed and it will be pretty easy to get an idea what's going on.

I'm leaning towards hardware issue too. That's why I figured I'd post and see if there was anything else that I can try. It's also why I don't really want to buy an expensive battery since who knows what it'll fit next. I know what you mean about the reboot battery boost. You can almost gamble and bet on percentages when you reboot. I've seen 50% swings before.

In recovery I would guess that it wont take very long to charge to full. I have battery monitor widget installed and while plugged into the wall with my 1.0A charger, it will typically pull 100-200mA but sometimes it'll spike to 700-900mA. No rhyme or reason. When idling and functioning properly, without a charger plugged in it drops 9-100mA. Sometimes though while charging it'll sit at negative 100-200mA.
HA! Just rebooted my phone and it went from 68% to 100%. So I rebooted into recovery, it also said full so I wiped stats.

I normally get 2 to 3 mA drain with the phone sleeping. When charging you may not necessarily get close to the 1 A current delivery of the charger straight away, typically it will ramp up over time and reach peak charge current as it gets closer to 100%. Once at 100% it wants to just "trickle" charge to maintain 100% charge until the charger is disconnected, so any wakelocks etc. that cause a current drain during that "trickle" charging will actually decrease battery charge until the charger ramps up to compensate for the drain. Random spikes in charging current would suggest a hardware problem where the electronics are struggling to properly govern the charging process, as would a large negative current drain with the charger plugged in. Silly question but what's the actual plug connection to your phone like? Nice and solid, pins all OK?
