2250mAh battery - not performing good!

I purchased a new 2250mAh extended battery recently from megacapacity.com.
In a full charge it gives me 18-20 hours backup with 1 hr talk time only. I don't even use Wi-Fi, GPRS. Just simple calls.
Is it normal? i dont think. Original battery 1050mAh gave better performance when it was in good condition. What could be the issue?
I have tried almost every ROM but its almost same in every case.
Anybody having 2250mAh battery? pl share your thoughts.
Is there some problem with device not charging optimally or battery is bad?
2250
I have a 2250 battery purchased from megacapacity itself. The first charge lasted for 50 hours. The battery at the time of recharge was around 20% but I recharged again. I am sure it would have gone for another 10 hours at least.
This is with moderate calls, browsing, solitaire, always on Microsoft Push mail and lot of email reading and writing. I was basically testing the battery backup; so kind of stressed my phone a bit to see the actual backup time available.
On a related note, I was definitely not happy with megacapacity as they didn't send me the correct battery cover for vox and never responded to any of my emails. So now my phone is without battery cover. And I am planning to buy one more normal sized battery because of this. Thanks to megacapacity.

PS: - I am using fireburned 6.1 stable rom 1.4.
I am pretty happy with Polar CEll 1300 mAh battery. It gets me through the day with heavy use! It dies when I am IMing over Wifi for a couple of hours in the evening.
Is it device charging issue?
My device was also working good with original battery. I used it for approx 18 months. After that (couple of months back) it started giving problem shutting down device suddenly while in the call. Its calibration was totally disturbed, i happend due to high temperatures some time when in car, i think so.
In nutshell that battery was of no use to be thrown out. Then,
I bought 2250 mAh but its not giving expected performance, its lasts for max one day with normal use.
Could it be due to issues with device charging circuit? It gets charged fully in one hour. i suspect there might be some issue with device circuit.
or finally battery is not good?
Pl advise.

parthabhatta & h4waii,
You both have good experince with VOX battery, pl share your thoughts on this.
Hi,
Actually I use a battery bought from megacapacity but its 1100mAh. The battery is not giving me any problems and after a few calls, roughly one hour surfing and some music playing 20-30% battery is still left. So what I feel is being 2250mAh it should last atleast 80% more than 1100 mAh if not double. You can check the Power management battery bar while charging - whether it shoots up occassionally at random or gradually increases with increments of 1% till it attains 100%. If it shoots up, try with USB charging and see if the problem recurs. Give it a try and let us know.
Just be careful of using BIG battery.

Thats a good idea, sure i will check and let you know.
I charged my 2250mAH in an external charger, which removes any possibility of the device shutting off charge after it reaches a certain voltage. It allows the battery to make that choice. I had good use with it, very heavy usage and it would last drastically longer than the OEM 1100mAH unit. I'd recommend just buying a 1300mAH as the 2250 is very cumbersome to carry around on the device.
Again, I still have mine - if anybody wants to buy them.
There are a few issues with keeping the sheet in contact with the pins, else it will shut off randomly, I padded it with paper and pulled the pins out a bit.
i got mine a year ago from ebaystore dmc-batteries.
first i also got the wrong backcover, but they sent me very fast the correct one.
The battery is definitely not twice as strong as the original one.
At normal use I think the max is 1,5 day. Light use gives me 2 days but heavy use with bluetooth or wifi or gprs only 1 day.
as h4waii I had in the beginning some problems with the contacts and sudden loss of power because of that, but that disappeared with time
Still I can't make a point...I'cant determine were is good to buy (obviously referring xda user's opinion to how much the battery lasts) and where is better not to buy. LoL

dmc-batteries gave me good service and are quick and friendy in their replies. I recommend them.
Thank you birdibird , but my intention was a survey to know what brand (seller) of ezxtended battery lasts more than an other. Just that
Because I've read of battery lasting 4-5 days with normal usage and others not lasting more than 1!

[i9003] Battery life and charge time

Hi all,
Whats the battery life you people are getting? and also the charge time taken for a full charge. Lets dedicate this thread for posting details about battery life.
Mine is below,
Battery Life : 1 to 1.2 days.
With live widgets and gtalk : less than 22 hrs.
Avg charge time : 4 hours(Too lond )
I got 14 hours with 4hours of wifi...anyway to increase battery life...even when its idle it dropped from 100 to 80...that is without use,is it normal?
Sent from my GT-I9003 using XDA App
Yes its normal & that happens bcoz your data connection remains on which eats battery, if you want to increase battery life you can use free APNdroid widget with this you can switch ON/Off the data connection. Else use juice defender or tasker they both can save battery life to quite an extent. Both have trial version.
In the night I switch to airplane mode & keep my data connection off hence I get 1.5 day of battery usage sometimes even more, if I don't surf the web then I get full 2 days of battery usage.
Charge time 4hours but I have heard that HTC charger can charge faster & gives longer battery life due to current difference. I will try this weekend borrowing it from a friend.
I think I am the first one to Vote. My usage is mainly calls. 1-2 hours of calling. 1 hour at XDA using XDA application with 3g on. 1-2 hours of playing around with the Phone and gallery etc. But with heavy usage, battery life is just enough to come back home and charge after 8 PM. My battery goes down by 3-4% after over night standby not 20% as mentioned in the above post.

This is more dependent on the tower distance near your home & its data signal strength, there are people for whom night time usage is only 1-2% ideal.
Do you feel if i flash a different firmware i would get a better battery life...

Usage without much gprs usage i get around 2 days.
Usage with gprs usage of about 3o mins surfing, email sync, lil chat & fb i barely get thru the day and am at arnd 15-30% by 7pm.
I guess mine's pretty bad eh ?

switch in the night to airplane mode & see how much drain happens.
Well, I have a moderate usage of almost all features (call,mail,camera,music,net radio,browsing,etc.) and it lasts for about 1.5 days.
Yea, full charge time is pretty long if you do not switch off your phone while charging.
Battery life in the long run depends if you have maintained a few golden tips for new batteries:
After unboxing, fully charge the battery in switched off condition. For the first 10-15 charge-discharge cycles, let the battery fully drain and the phone to automatically shut off. Then charge fully and switch on the phone. Avoid charging while phone is on or has quite a bit of charge.
I had a Nokia N91 and following above steps, the battery gave promising backup even after 4 years! Sadly, I lost the phone in Jan this year and bought the i9003.
DEAD CHARGER
Recently my i9003 bundled charger got fked up somehow... it just stopped charging the phone; had a few languishing days charging off the data cable off my laptop. Took to nearest service centre with a photocopy of the bill and it was instantly changed with a similar 700MA charger but of different shape.
Oh, I seemed to find a friend who is the tech there and jumped the long queue! LOL
I get about 24-28 hours battery life. I calibrated my battery after flashing to XXKB3 and I think that brought the best out of the battery. Running SuperPower and I mainly use Wi-fi while surfing.

how long is ur charge time with 700mA Charger?
I agree with the OP about seriously long time to charge! I had an X10 earlier and that used to fully charge in 2.5 hrs, but this takes really long. To just reach 100 from 90 it takes like about an hour!
well mine since i flashed 2.3.4 only stays for 18 hrs max with less than average usage only talk in for 1 hrs 2g maybe and browse use ebook for 1 hr maybe that is all when i used froyo 2.2.1 it used to stay for 1.5 day
any ideas of wht i can do i did battery calibration and am using xda super power
on xxkph i was getting about 15hrs with amits oc 1.1
after flashing xxkpm i seem to be blown away
im using xxkpm and cf root by skin and im getting 1 day 5 hrs with heavy usage and 2 days 4 hrs on moderate usage
well mine is jxkp3 cause it have arabic in it's languages but do u think this could be the reason why my battery is so low and fast drained it is also rooted

seriously,how do they search these threads!

I actually like my Sensation, but I'm gonna have to return it

Kind of makes me sad though. The device feels good in my hand and I like it overall, but the battery performance is unacceptable for me. I went to bed with it having something like 93% (dropping from 100% after like 15min of play). Not even 6h later I wake up and when I look at it, the battery is already drained to 85% only from standby (Yes,always-on mobile data is deactivated, power efficiency is on). After playing with the unit in train and some browsing while commuting for 30min, its already at 70% or something. During the next few hours, while working, I was just checking mails, using whatsapp from time to time and writing a few messages. No surfing, no videos no games.
By 3PM the battery was at 15%. Even worse, the damn thing takes some 4h+ to fully charge. That's just too damn long, my iphone 3gs charges fully in about an hour. What is also very frustrating is that the Sensation discharges a good portion of its current as pure HEAT. Never saw a phone get this warm afer 15min of normal usage.
I knew battery wasn't going to be stellar but this just sucks. Most of all that a full charge takes 4h. fail :-/
EDIT: Ok guys the 2.3.4 update did the trick! The battery now chrages fully within 2h and battery life has ridiculously improved!
I took it off the cord around 8am this morning. Now it's 2pm and my battery is at 83 with some 46min screen time and slight usage. Also the heating seems to be gone.
Apart from that, everything runs smoother with the new update. Guess I'm gonna keep the little guy after all
However, I did order 2 extra Ankers + charger (25$!) as additional mobilty is never wrong.
Before you return it, I recommend that you call HTC support and request a warranty exchange for the phone and battery.
You may have a defective unit.
While my battery isn't stellar, I get a minimum of 10 hours before I drop below 20% life (always-on mobile data off, manual syncing, not too many widgets).
Your phone battery performance is not indicative of Sensation battery performance for the overall majority.
Most have said that the battery gets better after a few full charges/discharges, and the todays new update is supposed to improve battery performance. Many people say the Sensation is better than most other 4G phones.
I dont play games and such, mostly phone text and email and it lasts me a day and a half. There is also a better battery you can get.
That charging time is ridiculous, which leads me to believe that your unit and/or battery is defective.
Mine charges from 15% to 100% in 2 hours. Same for almost everybody elses phone.
You might want to reconsider and try warranty exchange mentioned earlier. Also, I would suggest the ChiChi battery. I'm running from 7:30 to about 4:00 with my WiFi hot spot turned on for my Galaxy Tab 10.1 and I'm using my phone for calls, texts etc., my battery still has about 30% left when I leave work.

Dude , custom rom and anker / chitec battery.
My first time with my new anker achieved almost 24 hours on battery and almost 4 hours screen time with quite alot of use during that time.
Totally destroyed my oem battery in every way.
Also I would do a Warranty Exchange and with the new update I have seen a big differance in 2.3.4 vs 2.3.3 in terms of battery life and speed of Sense in general. I purchased a Anker 1900mah battery for $10 and fully charged to dead I get on average about 17-20 hours and I would say I'm a good moderate to HEAVY! user. Switching back to a stock battery after calibrating with the Anker Battery has also improved battery life seeing that I get between 12-14 hours with stock now. I would charge to 100% go to bed and wake up with about 97%-98%

+1 I agree 110%, Try this though Calibrate the Anker Battery then fully charge your stock battery and see what battery life you get.

Get a anker battery and download leedroid/android revolution/insertcoin. I guarantee you won't want to return it than. When I first got my device I was thinking about doing the same thing but after I looked through the thread I saw people were getting better results with the anker or chichi. Don't be discouraged that its a third party. It actually out performs the stock battery and embarrasses it.
Also download calibrate battery from the market.

I had terrible battery life for the first week or so. 6 to 8 hours max, and 2 hours screen time if I was lucky. After conditioning the battery by fully discharging then fully charging on the AC adapter for a few cycles, it corrected itself for the most part. Yesterday I had 15 hours with 3 hours screen time and still had 20+ percent left. I have a chichtech battery sitting in my mailbox right now waiting for me to get off work.

After I got my anker I sold my OEM and got two more. I also have a evo3d battery that I haven't used. I also have been hearing good things about it.

really appreciate the good advice guys, thanks. I have done my bit of reading here and many many people here report having around 4h charge timr (http://forum.xda-developers.com/showthread.php?t=1154780)
So you guys can not confirm this? If so, it might be my battery is faulty. I will upgrade to 2.3.4 and calibrate. Probably will improve battery time, I doubt however it will reduce the charge time...
Something is definitely up. I just got my Sensation 10 days ago and am still stock. It takes me ~2 hours to fully charge, and that's with me using the phone like crazy while its charging....and the phone light on the entire time.
And I get a good full days use out of it....sometimes 2 days if I dont use the screen much and just phone text email.
IT'S ALIVE!!!

Also check if your phone is always awake because I had this and it had a huge affect.
I easily get 16-20 hours with LeeDroid's ROM.
i had the same battery issue with my first sensation. Even after several cycle of charging - discharging, battery calibration, the battery would not last for more than 7-8 hours. i exchanged it , for first couple of days, it didn't hold the charge for long,.but after i did battery calibration and update to 2.3.4, now my battery will last for 12 to 14 hours with moderate use. doesn't get hot with normal use, but over the weekend , i use map navigation and temp reached 48C. I think, i should not use it as GPS for longer than few minutes, or it may burn the phone.
Juice Defender Ultimate is definitely worth the tiny amount of money it costs. Just got just over 3 days on my Sensation, admittedly i hardly used it.
Usually i get a good 22 hours from it with medium use.

Just replace the battery and you will see the difference.. my phone last ast least 10 hours.. its just amazing....
I lose almost no charge while it sits on standby.
I work 12 hour shifts, I listen to Music the entire time, browse, login to home computers for about 30 minutes using Teamviewer and keep up with RSS feeds throughout.
By the end of shift I'm down to 5%.
Sounds like you need a replacement, rather than a return, bud.

Battery Issues

The battery's been running wild since a month on my Pico.. so finally i managed to capture some screenshots and here they are..
Keeping it for 2.5 years now, it gives a battery time of around 5-6 hours standard. i have to recharge it twice or thrice daily and a recharge takes around 3-4 hours (thats insane).
Pretty confused on the battery timings as i see weird timings and battery level on my cell, check out the screenshot this will give you the actual idea how much time it takes for me to charge, check out the Battery Level and mAh and let me know what you feel or in any way you can guide.. is it time to buy a new one or not?
I'm rooted on CM10 and in no way application's sucking up my battery, i can guarantee that!

Battery life, how is your phone doing?

Wondering how is your battery life, I'm 5:30 hours for 54% of battery(75% - 21%)
I max charge it to 75% and usually I don't drain it less than 25% - To achieve the best battery life long term, so I won't need replacement anytime soon. Also I don't fast charge, usually 1A charging or similar(e.g. Wireless charging 7.5W)
Obviously I use underclocking to the point I don't fee any difference in daily usage
Share your thoughts, for 0-100% I bet I can do more than 7:30 SOT

Lol mate you're more like 5:30 min after 75-25 twice.
Such a bad battery life usually happens after using mokee as they change low lever instructions in the processor.
What happens is that the processor microcode is changed such that instead of power being managed by the relative motion of conductors and fluxes, it’s actually now managed by the modial interaction of adreno-reluctance and capacitive directance of the cores. You can not change that any more as it was a change on hardware level microconductions that can not be reverted.

50%(75-25% usage) of battery gives me 5:30 SOT hours and it's bad?
You troll right? this is only achieved with underclocking, at 100% you should expect more than 7:30 and maybe 8 hours! what about you?
P.S. Give me your SOT 75-25% and if it's more than 5:30 SOT I'll send you my phone for free - Bet you can't even do 6 hours SOT with full battery
just look at the screenshot you provided yourself, the battery graph clearly shows you charged your phone after you hit 25% the first time to 75% and let it run down to 21% again. battery (and sot) stats won't reset until you charge over 90%, so your reading of 5.5 hours of sot is actually 2 instances of your habitual 75-25% drain. in reality you are only getting about half that for 50% use (~2h 45min sot), which I'd say isn't too bad, but maybe you should do a full 100% to 0% use once and see how the battery fares for a more accurate reading. honestly I would say you would still get around 5.5-6 hours sot from that, and that unless you do some serious tweaking to both your phone and usage patterns you wouldn't be able to hit 7 hours sot, but I would be willing to see evidence that proves me otherwise.

Battery Charge Limit - Resets your stats but also limits the charging
I know you are clueless but talking without knowing is bad - 5.5 is for 50% battery due to high underclocking I've got
With 100% I can get over 8-10 hours - High end CPU cores are not more than 1.5Ghz, gpu at power saving but also lowest possible freq for min/max - You are talking crap but ok I won't feed you, I stop feeding trolls the moment I get they troll
sorry but you are the one talking crap, please see attached picture, which is a crop of your battery graph. i personally also use the battery charge limit app, and i know how the reset battery stats option in the app works, which will clear the battery graph as well. if you really did clear battery stats you wouldn't be able to see this upward curve.
how about this, you fully charge your phone and use it normally until you hit your claimed 8-10h sot. honestly i think i can match your sot, but without this underclocking you highly praise.
You're either braindamaged or a troll. You charged your phone and it didn't reset stats so it combined both usages. Did you pass 6th grade maths? Anyways SoT is subjective and you're just being extra petty about this

Only 10?
By doing a small mod on the battery, I get like 12 hours minimum, with 50% brightness fixed. What I did is that I replaced the main-winding of the normal Lotus-O-Deltoid type and placed it in the pan-indermic semi-boloid slots of the battery.

Removed lots of bloatware using adbFastboot tool and connected mostly on wifi. Without wifi with medium usage, I can get around 6 hours SOT within 2 days of use.
aex + canting.
I've had mine for 18 months and am still very pleased on the charge. I can typically get 12 - 14 hours fine, and that does me for most uses. I've seen it go longer when I've used it less (for example right now 20 hours without charge - 6% left, although that would include about 7 hours of sleep so no use in that time).
No modifications on my part.
