4800mAh extended battery problems

I've found that the current stock battery for the HTC uni is simply too sh*t, that being said, i have purchased an extended battery (4800mAh)
I've had a few problems now. First and foremost, if i leave it to charge overnight or similar, it will say 100%, but if i unplug the charger, it will say 31%. What the f*ck.
I ran some tests on it (batterybench.net) and i seem to get 241 minutes with only radio on. That doesn't seem right for a battery of this capacity.
I also purchased a 3200mAh battery and encountered similar problems in regards to runtime. Is there something wrong with my phone? I've turned off beam and all that, underclocked, bla bla, i still seem to struggle. Any ideas?

thats not a device battery problem.
your charger is faulty.
charge your device via usb(connect to your computer) and when it shows 100% be on the battery screen only and then plug usb.
else flash another rom and see,if you are still not satisfied.
i faced this problem earlier with my htc adapter for my htc gene(p3400i).
So its not a battery problem.

Thanks, but unfortunately that doesn't seem to solve the problem.

I tried 4800 battery bought online, however it only lasts 8 hours, then I finally got a standard replacement battery through a HTC dealer, and it lasts TWICE AS LONG as the so called double battery??

Move to accesories
There is a proper place to discuss this topic

As I said before - 3200 mAh battery is the best, don't buy 4800, it's a crap

[Q] Why Sensation take very long to recharge the battery...

Hi,
I didn't know what happened.. what My Sensation now take about 6 to 7 hours to complete from 15% to 100% while before i just took 3 hours to complete the charging...
Edit: I knew the reason .. I used Nokia charger and it take more time (double) than the Original HTC charger.. i think mainly because of the charger...

possibly bad hardware, or a ****ty battery, i get full charge from 2% to 100% in about 3 hrs

I had the same problem, sometimes it goes fast, other times it just takes ages, aslo got the non responsive touch screen issue oh, and gps won't fix, it cant find more than 5 sattelites, hurray!

I'm getting this on mains charging now also.
Not sure why - has anyone tried a "power off" charge versus a "power on" charge?

I always charge my phone power off. light to moderate use I get at least a day before charging.

Maybe that's firmware dependent. Some ppl noticed the same but after updating from 1.28.xxx.x to 1.35.xxx.x battery performance, battery monitor behavio(u)r and charging time are improved as well as other bugs fixed. But it's not officially released yet.
HTH

I'm using the 1.35.401 update, and still have this problem, aswell as bad gps reception, high battery drain, and long charge time.

im rocking 1.29.531.2 stock for my fone, and no problems with the battery at all, quick charges, and good to great battery life.
as for the GPS, i think everyone is having that issue right now, the most i ever got was on a completely clear day, 7 satellites :/
my HD2 after running the canada fix thru CWM got a minimum of 12 or a clear day
lucky for me i dont use the GPS that often, if ever
EDIT: also, im using the stock charger about 3 out of 4 of my charges, the rest are from my lappy via usb

It's slow at charging. Get the wall charger from tmobile or use a Samsung galaxy s charger. The galaxy s charger will charge it way faster than the stock htc charger.

I can honestly say that it takes mine about an hour longer to charger while power off than while power is on, don't know y tho. So now I usually just let it drain to about 3% n then charge it..

If you want your battery to last longer you shouldn't let it drain more than down to 20%, due to the nature of the lithium battery

its actually a fact, most ppl who have used Li-Ion for at least the past decade know that if you want the best performance, dont let it drop below 15-20% before charging, for optimum batter life and sustainablilty.
same thing goes for if you arent going to use the device for a long time (min. 1 month) charge it to around 50%, then decomission, and the battery will "keep" very well
EDIT: because flamers love their link complaints http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

with 1.35 chargin is much faster. really it's already available ota for unbranded, branded phone owners need to w8 for their carrier ... :\

i'm interesting by your proposition,could you explain why galaxy s charger is faster than htc charger?
i use to wait 3 hours(-+) for 25 to 100 pcent, how galaxy s charger is faster?
thank you!
ps:sorry for my english but look at my location!!!!!

It charges faster because it charges faster. Lol
Idk why it does, but it does. It's the same for my hd2. A friend gave me the galaxy charger for a extra. I tried the charget and it just charged faster for my hd2. So when I got my sensation and saw that the stock charger was slow like the hd2, I tried the galaxy one, sure enough, it was faster too.

Thanks for your informations...
Just got 1.35.163.1
Some people says that improve the charging time.
I will report this tomorrow.
And i will test with sgs charger too!

I have a US version stock. As you know we have no updates yet and no s-off. My phone charges fast sometimes, other times it can be on the wall charger for 6+ hours and not be fully charged. I think its a software issue honestly.

Yes as said earlier recharge when it's at 20% the battery will hold much longer the batteryuniversity is my source too Also spare batteries should be kept at 50% and kept in the refrigerator when not in use.
Hmm the new update didn't do much for charge time for me though.

the charger that comes with the sensation is ~1A which is kinda slow when the phone is on, not as bad as others with only 500mA usb... you should be able to find a usb that give a higher A output and still retain the usb plug (ive seen 1.5A before cant remember where)... failing that if your ingenious you can splice through a different charger and make your own.. could achieve 2A+ but your could burn ya house down or blow your battery up in the process

Infuse charging stopped

I had the infuse on the AC charger the other day, when I took it off, it had a message stating charging stopped because of battery temperature. Now battery will only charge to 35% no matter how long its plugged in. Also when phone is off the charger, phone is getting very warm to the touch and the phone is not being used. Do you think I need a new battery or is the charging circuit messed up? Thanks for any input!!!

If your able to plug it in and it shows it's charging then there is noting wrong with the circuitry. Your gonna need to replace the battery.

A new battery is much cheaper than a new phone.
Batteries heat up as the internal resistance increases over time. As Axiomkid suggests, get another battery. Do it soon. Old (or defective batteries) overheating run the risk of shorting, leaking, or exploding.
Better yet get two batteries and maintain them properly ie discharge to 10%, recharge to 100%, then swap out with another battery and let the recharged battery cool down.

Tried a new battery, it charged to 100%... but drained 50% in one hour. When I charged it again same problem is still happening. Thanks for all that helped.

You might need a new charger too. are you using the original Samsung charger? Try charging it from a PC too. The 50% drop in the charge could be a calibration issue too. It would improve that reading over the first few charges with the new battery.

yes i am using original charger, i have use a captivate phone charger as well. i think they are both the same. i'm thinking something is wrong with the phone because after charging and taking the phone off, the phone is getting really hot without being on the charger. like the phone is being used but it's not. could maybe the rom cause an issue like this? i'm thinking maybe trying to flash the phone with a stock rom and see how much the battery drains

Problem solved!!! Reflashed ROM and all is good

Glad to hear your problem is solved! Was that the root cause with your first battery as well?

[Q] Battery Issues

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?

[Q] Question on Battery charging and temps

Hi i bought a used sensation of ebay from a reputable seller and it arrived the other day. The two main problems i've been having is also the battery taking long to charge and the heating issue.
Firstly im not sure if the heating issue occurs on stock rom as i was not on it very long but on any custom JB rom the Bottom part of the phone gets very hot very quickly. I used a battery monitor and it tells me its the battery temp that's going up but when i pop out the back cover it seems to be coming from right at the bottom under where the micro sd card is. However i think i have kind of solved this by flashing the Inspiration 1.01 ICS 4.04 rom with bricked Kernel. Now the phone only reaches a max of abut 40.5 degrees and the heat is spread around the whole back case rather than one spot.
Secondly the battery seems to be the big problem here. The phone didnt come with a charger but it did come with a USB cable to charge with. The problem is when i plug it into charge it takes long time to charge up. I used a battery monitoring app and the results are quite weird. When i plug it into charge it starts of drawing about 300ma of charge but after a while especially when it gets to around 30% battery the amount of power the battery is absorbing is around 70ma some times even as low as 40.
I have tried this with a Motorola charger as-well which is from a Motorola defy mini which had a higher Mah battery and the same thing happens.
Bearing in mind its a used phone the battery is probably quite old shall i try my luck with a new official replacement HTC battery or shall i try a new HTC Charger first?
Quick Update:
i took out the battery and then put it back in again and turned on the device and now the phone is reporting 65% when it was only at 47% before i turned it off. Secondly onthe battery contacts there seems to be a darker colour of gold where the pins actually meet which looks like a burnt contact but im not too sure.

I highly suggest you buy an Anker battery instead of HTC official one. If you've been loading battery with USB cable from another device (PC for example); it will load slowly!
About the battery percentage problem; I think this is a known problem on HTC Devices. It should show pretty accurately after a little while after restart.
I myself have the original battery, and I have the darker marks there too. Don't worry about those.. Because all you need is the Anker 1900mAh.

Thanks for your suggestion i have done a bit of research on the anker battery and it definitely seems like a must have not only for the better battery life but it apparently runs alot cooler than the stock battery aswell. Only £21 for a pack of 2 and a travel charger on amazon aswell!
Also shall i get a HTC charger or should i be fine with the Anker travel charger?
