Larger capacity batteries - any good? - iPAQ rw6828, XDA Atom General

I was browsing on eBay and saw that there are higher capacity batteries avaliable for the O2 Atom in 1600, 2200 and 2400mah. The later two seem to include a replacement back cover as the battery is physically larger. Just wondering if anyone has used these and if there any good as battery life isn't so flash with the Atom?

I had one for my old Wizard - it did last a long time, but was pretty unsightly. Just for those occasions where you're away from home a long time (I used it when sailing)

Neither the look or larger size worry me if it's going to make a decent improvement to battery life.

copy/paste from this thread : http://forum.xda-developers.com/showthread.php?t=336075
Just before my Atom went to PDA heven ,
I bought a Mugen extended battery.
3000 mAh
came with 3 new covers (black/grey/white)
worked a treat , but did double the width of the phone
(can show you pic's if you like.)
Bought from a member of this site, who is one of the top 5 donators.
Australia based.

can highly recommend them .
(safer than e-bay IMHO )
After using this battery , I can say the 3000 mAh will last Almost double .

HERM Batteries

Just noticed that my herm300 came with a herm160 1300mah battery. Is this typical as I note it should be the 161 battery. It also seemed to be fully charged and unwrapped in the box, I have a feeling this could be a used battery.

There is a post or perhaps on the wiki somewhere, details about the two different batteries. Just from memory I think it depends on the particular Hermes model you have.
I think it's quite normal for battery to be charged on receipt, certainly mine was - though I can't remember if it was wrapped or not.
Mike
just got 2 delivered today and they were both charged, but wrapped.
Were they HERM160 parts? I wonder why they changed to the 161 part, I guess they may have two suppliers and put whatever is available into the box.
There's a thread on this over on the Cingular Forum.
http://forums.cingular.com/cng/boar...essage.id=25601&view=by_date_ascending&page=1
Looks like the 1300mAh battery is getting more poitive ratings.
whats the difference between a herm200 and a herm300? version? mine is brand new today and in device information it says it's a herm200?
bit off topic, sorry
It's just cosmetic really, the 100, 200 and 300 are the various operator customizations. Apparently the HERM300 should come with a 1350mAh battery but looking around it just seems to be pot luck which battery you get.
My Hermes is a model 200 Spanish and comes with a 1300mAh battery manufactured by Sanyo. It usually runs for a day... but I use the machine a lot during the day.
I'm not dissapointed.
My 2 weeks old herm300 came with a H160 - 1300mAh battery made by Sanyo. Bought it from Polish ERA operator as MDA Vario II. No batt problems so far, after initial discharge/charge cycle working times are 3-4 days of not so heavy daily use: short 3G and WiFi sessions, +/- 20mins of phone calls, 2-5 SMSs and usual calendar and tasks activity.

Anyone know how well this extended battery does?

Anyone have any idea how good this extended battery is for the Tilt?
HTC Li-ion Extended Capacity Battery with Black Extended Battery Door
Product Details:
HTC Li-ion Extended Capacity Battery with Black Extended Battery Door:
The aftermarket AT&T Tilt li-ion battery includes a black extended battery door. This AT&T Tilt Battery requires two to three complete charge cycles to reach full performance and is rated at 2400 mAh. The AT&T Tilt Extended battery is the perfect extra or AT&T Tilt replacement battery.
Compatible with: HTC 8925 / AT&T Tilt / TyTN II / HTC Kaiser
Is this one good or does it have issues like the others that have been mentioned with the power readings?
Just curious cause could really use an extended battery and would like a reliable one, if there is any.
Thanks,

Tilt Extended Battery?
I have heard some mixed stories about some of the extended batteries from actualy users.
First looking at the 2800 size battery:
http://www.amazon.com/AT-Tilt-Elect...=wl_it_cm_cr_acr_txt?ie=UTF8&showViewpoints=1
"This larger battery lasts about 1.5x longer, so around 15 hours (or more, I haven't let it drain completely, yet). This wasn't a huge increase, but it does let me use the phone for roughly a full work day. My usage includes push e-mail during the day, with numerous incoming and outgoing text messages, and maybe 30 minutes of talk time.
Charge time is excellent in my opinion, it took around two hours to charge the battery from 20% to 100%. "
Next I was looking at the 3200 size battery but couldn't understand why the price on these were so much higher than the 2800 for the little extra run time that you are getting.
http://www.amazon.com/Mugen-3000mAh...dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1
"PROS:
- the battery fits in the phone perfect
- the new back cover given is high quality, fits nicely, and looks great
- the new battery and back cover combo makes the phone thicker, obviously, but it is not over-bearing and easily noticable to others
CONS:
- just one, but it is a big one. so, the original battery is 1350mAh, right? well, that wasn't getting it done at all. we're talking 8-10 hours a charge with minimal phone calls. i do have exhange push email and another pop email that i am checking. that is most of the battery drain i imagine. fine, so i saw this and thought, "perfect, 3000mAh! this should get me a whole lot more time". well, as i finding out, not really. to be fair, i am getting more time. i would say 12, maybe 14 hours. a net gained of 4 hours. that seems strange to me for a battery that is 2.5 times as big. anyway, just want to give you a heads up so there isn't too much disappointment. PS - i did the whole "battery training" thing where i charge it all the way up, ran it all the way down....etc. 4 days in a row. "
So hope that helps...
I just hope this with an emergency charger, http://www.amazon.com/Battery-Charg...UTF8&coliid=IR8PJ5939FJ0L&colid=3UMYZBAJT4AYL
helps me get a full day with my unit...If this doesn't help I might consider the Iphone because I hear that is getting a full day of juice with one charged regular battery.
i was useing a 2400ma extended battery it worked good other than the door would catch on the part where the extended battery was sticking out pop the door off knock the battery out and turn off my phone. it was such a pain in the butt that i decided that i would rather charge my phone everyday than look in my holster to find my phone had been turned off for who knows how long. i was thinking about getting this battery though next time i feel like i have money to blow. http://www.amazon.com/1600mAh-Exten...1?ie=UTF8&s=electronics&qid=1226420513&sr=8-1
I bought the 2800 Mah battery. And it came with a ugly back door so i order the nice door that looks similar to the orignial cover. Well the 2800 works better and last longer. it mite last longer n better if you have a custom firmware. cuz im running the 6.1 n i heard the battery dies fast from it. But with the extended battery my phone dosent die fast.

Battery Lifetime

How does the battery behaves when compared with HTC HD and the original Diamond?
I found a good review article of the diamond2
"In terms of battery life the Diamond2 promises nearly double the amount of standby time over its predecessor. From my time using the Diamond2, starting with a full charge and with frequent use (web browsing/ music/ camera/ the excellent bubble burst game!), the next time the phone needed charging was five days later and even then this was more of a top up rather than the battery running on empty."
(http://www.mobiles.co.uk/htc-touch-diamond2-review.html)
i cant quite beleive a 5 day battery life on this phone! if it is true then it will be awesome but it has a smaller battery 1100 mah against 1350 in my phone currently which i get about 1.5 days out of it.
So i will be reserved, and slightly pessimistic

I would expect it to perform like your current phone (the HD, right?). smaller battery but smaller screen, so it should be about the same, and the htc provided data seems to be in line with that (about the same stand by, talk time and video talk time...)
So I think u are right to be pessimistic, but I also think that a higher capacity battery is possible with the same size as the 1100 mAh one: This TD2 battery is large, compared to the TD1 one: about 2 times as large, and TD1 was 900 mAh. Except if they are not of the same thickness, TD2 battery should have a higher capacity than just 1100 mAh...
I found nice shots comparing internals of TD1 and TD2, where we can see the 2 batteries
http://www.mobile01.com/newsdetail.php?id=7317
I do not know how TD2 battery compare size-wise to the HD, maybe you could post some pics of your battery? side by side shots of TD2, TD1 and HD batteries would be very nice, especial it we also have thickness shots anyone having acces to the 3 care to post those?
gkai, no i dont have an hd, i wish i had one. I only have a polaris which is why i cannot understand the 5 day battery life as if my current phone does not last that long. I think that something that is more powerful, bigger screen and a smaller battery will last as long, i just dont, and also mine is stated to have a 400 hr standby time and the td2 only has 360 hours.
So i will still be pessimistic and say that they had some wonderous phone to get it to last for 5 days! (or didnt touch it for about 3 days!)
also the physical size of the battery does not actually matter the rating of the battery is what matters and that is smaller therefore a smaller battery. The td1 i think was always said to have a really bad battery life so hopefully htc have heard this and made the td2 better with a longer battery life, we can all live in hope

hum, then it is possible: faster processor does not mean that it will drain battery faster: new generation are etched finer and use less power for same or more processing power. Screen can be (slightly) more efficient, and power saving of the different radio can be better too. But I expect the phone to be good for 1.5/2.5 days of typical usage, no more, given the current behavior of the HD, touch pro and touch diamond (which have almost exactly the same internal components)
So i will still be pessimistic and say that they had some wonderous phone to get it to last for 5 days! (or didnt touch it for about 3 days!)

The second is more likely, I doubt htc has changed the battery for the review (although it is possible). Good cell coverage is also good for battery life, if u have a cell tower nearby your phone will get better standby and communication time, same for wifi. I guess they both were in ideal condition and used the phone lightly...
also the physical size of the battery does not actually matter the rating of the battery is what matters and that is smaller therefore a smaller battery.

hum, yes, it is the rating that count...but given that all good batteries use the same technology (lithium-polymer), mAh rating should be in direct relation with physical size: a large battery with small rating just means that your battery is of an older generation (unlikely), or that there is a lot of dead material (plastic packaging) in your battery. So either the TD2 battery is much thinner than TD1, or it is likely that higher capacity batteries with the same physical size will surface quite soon on the accessory market (I hope for the second case, battery life under normal usage is one of the most important factor for me, it is convenient to have more than 1 day of "heavy" use per charge, and less than one day under "normal" use means the phone is poor for me, whatever its other qualities...)
Bettery Life!
Hi Guys.. Wel 4 days in, and still on my first full charge!
According to the power screen, I have used
58 hours 25 minutes standby
Talktime 2 hours 22 minutes
device usage 3 hours 24 minutes
And stil have 4 bars left!
how to say i think that htc have finally sorted out battery problems and have made a phone with a good battery life. Seems like ive been told!

Hay there what settings are you using, ie HSDPA on? screen brightness settings auto or minimal? how are you using your device?

My standby time always more or less equals the device usage time, so 50/50. I keep playing with it all day At the end of the day it's at app. 50% charge.

0
Usage
1hour 28 minutes.
3 bars from the main power meter have already gone.

yes, my mistake However, my point stand: battery capacity should be directly linked to its physical size and weight, given that the technology and materials used are the same (especially if you compare the batteries of a single manufacturer, like HTC). If not, it mean that the battery is not optimal and that a higher capacity battery battery of the same size is likely to come afterwards (from htc or other suppliers). That's why I was interested in the physical size of the TD2 battery compared to other devices...Well, with some luck I will know today, maybe a batch will arrive this afternoon in my favorite mobile shop and I will pick one ;-)
After the first full charge and unplugging in the morning, mine lasted until the evening.
about the same as my D1.
I don't have bluetooth or wifi on ever.
So to be honest, with average use....it's still ****
Good job i bought myself a AA battery emergency charger for it as well
Extend batterylife
Maybe not what we're looking for , but it's a way to extend batterylife:
Just underclock your TD2 or other HTC-device:
Look here and here...
FYI: Overclocking is not possible (yet )!
@Juggles
Didn't expect to see you here, how's life? How's WmGurus?
So you have move to TD2.
How's it?
Good buy?
It's selling here from today in shops between SGD538 to SGD668. Maybe its a promo price.

How you've managed to achieve this I'd like to know. As currently I have 2 bars remaining and I have the following listed:
19 hours 1 minute standby
Talk time 0 hours 2 minutes
Device Usage: 3 hours 25 minutes
since my last charge at 23:25pm Yesterday. It's now 21:53. I have had WiFi and 3G on most of the day mind you!
7 DAYS on Standby within 1 full charge! (however without Sim Card in)

Long lasting battery ?

My battery on the x7501 is dying, is there a good and fast company that you can recommend for a longer lasting battery ?
Thanks
We've been discussing this lately in the Athena Accessories sub-forum. http://forum.xda-developers.com/forumdisplay.php?f=354
Go get yrself an external battery pack of 38000 mah and above , buy 2 if u really use it a lot , just leave the original battery inside or if it is really dead , get one oem replacement - cheap ones and use it with ext. batt pack , original htc ones dont really last that long either , so try save some $ , we hv to resort to all these bcos the original manufacturer unable to find more space for a longer and better battery - that's why , so we hv not much choice - jimmunsw take care n cheers
I bought a 2400 mah battery online from Mugen power (google search) and the battery is a direct swap (same exact size as factory) and it does last longer. I know it's just 200 mah more but it last longer than factory, from the time I take it off charger in morning till recharge time is about 12-16 hours, here is a typical day usage
- 70-100 min talk time (all though bluetooth)
- (gsm internet) email checks on four accounts
- (gsm internet) weather checks all day
- pda usage throught out day for calendar reminders, task entry & reminders and contact lookup (device on an off as needed - not on all the time)
- wifi usage to transfer files in my office network (network plugin)
- and sometimes about 30 min on wifi internet at night.
This is more than I used to get, the battery is about $75 US and comes with a desk charger, so you can keep another battery always charged.
anx7501 - just curious what ROM your using. Reason I ask is i think the ROM has a lot to do with how long a batt. can last. I have a new batt also but never get close to what your getting. Also how long have you had the new replacement batt? I may just buy that type of batt that you ave if your ROM is the same as the one I have.
thanks
My ROM ver 2.19.453.4, factory X7501 ROM (no flashing)
I've had the battery for 2-3 months now, honestly this is second one. I was a little too hard (physically) on this first and it started loosing charge rapidly. Nonetheless, they were very honorable about replacement - I mailed them mine, they mailed replacement (within one year warranty period). The one I recieved in exchange is now about 2-3 months old.
Mind you I now BABY this battery, I keep an eye on charge, when it's about 20% at night I put in standby, place face up until battery side is cool. I charge with device proped up to let air under. All this sounds weird but I find that it re-charges and holds a charge better when the battery is not hot.
I do get an honest days use out of it now.
Hi there again ,
it is nice to be in america and gets to buy a mugen battery for usd75 , pretty good n reliable n lasting quality battery , but for others if get from mugen , plus the express us mail or courier services , the total end cost will be around usd 130 - 140 ( let's say from usa to malaysia for example ) , i mean it really cost us a lot , our local seller will sell us an oem china made battery for usd17 each for 2200 mah with one to one exchange warranty for 12 months , basically it will last at least 75% of one mugen battery when new and after that it will drain it's efficiency and retain charge ,this depends on how one use the battery , one must pull the plug or switch off the current of charger once it is fully charge - from orange light indicator turning to green colour , if this is not practised , then battery will start dying soon . but yr idea of cooling off the battery standing up and also charging that way is quite a good idea , maybe i give it a try to see any improvement . thks for reading and all the best - jimmunsw
My current battery is over a year and a half old now, and I have always kept it plugged in whenever possible. My first battery lasted for 3+ years using this method! The rom does have a big impact on the daily battery life in these units! I used my phone alot and have usually gone about 2 days on a single charge when I have not had my charger with me. I use it with the bluetooth on all the time, and I check and answer my emails 4 or 5 times a day! The only times that the battery wears out quickly is when I use the wifi or when I play games on it.
Later...........
Battery Life
I'm currently only getting 1-2hras of battery life.
I used to be able to watch a 2 hr video with no problem. If i left it unpluged over night it was OK. Now I charge it overnight and it won't het me to wor (1Hr) playing music and reading. I think it has to do with setup or apps as I have 2 Batteries and they both do it.
Stock ROM. is there any list of apps that kill Batt life?
Thanks

[Q] High Capacity Batteries

Hi,
I think my original G1 battery is finally reaching the end of its days (it generally only lasts about half a day now - but it is two years old after all!).
My question is, does anyone have any experience of the 'high capacity' batteries that are for sale on ebay? Are they ok?? Do they really last that much longer??? Are the very high capacity 'chunky' ones that come with a replacement back cover that much 'chunkier' - so much so that they don't fit comfortably in your pocket anymore???
Any help/warnings/reviews much appreciated!
Cheers!
Hello.
I have 2600 mAh and it lasts really at least 2 times the original battery does. I can only recommend it. I also use great app Juice Defender, which prolongs my battery life significantly and I get 1.5-3 days of battery life, depending on my usage.
It is bulkier that original, people notice my phone as a large one, but I got used to it and it is not a problem really. It even somehow fits better in my hand. And easily fits into regular jeans pocket, no problem.
2600 mah is the way to go. Yes chunky is good. Fat phones need love too.
sent from my superfroyo dream
Thanks for the responses guys - I'll be making a purchase later today!
Cheers!
