Definitive Battery Thread

Hello everyone!
I've spent the past week doing as much research as possible into what type of battery to buy for my G2 and i've come across alot of information to say the least. Alot of opinions, alot of useless data, and some useful data. I just wanted to summarize this info for everyone. And add any new information that people post in the thread below, including battery life data.
Popular Batteries:
- The Mugen 1800mAh - $45 (1400mAh in testing)
- The Senido 1750mAh - $50 (1400mAh in testing)
- The HTC 1500mAh 35H00123-11M (-00M).. Also known as the TP2/EVO battery - $7 (1500mAh in testing)
- The CHICHITEC 1800mAh - $20/each or $40 for 2 + Charger (untested)
Research:
- Mugen and Seido seem to have EXTREMELY inconsistent mAh ratings, HTC seems to be the most consistent.
- On the other hand, trying to compare these battery assuming constant maximum power draw is a little unfair.
The one thing that seems constant is that HTC's battery's perform as expected in every environment and over time, whereas the third partys seem to be able to pull values closer (somewhat) to what they advertise under certain conditions. Not to mention that we have no knowledge regarding the long-term affects of the 'tuning' that these third party companies have done.
We gotta realize that most battery's are using the same cell or the same knock-off cell, and we can't really expect to much of an increase in mAh in this battery form-factor.
Installation Issues:
A lot of these battery's will need to be modified to fit our phones in one way or another as they're meant for the EVO 4G/Incredible/TP2/MyTouch3gSlide/CDMAHero.. Even the ones that are labeled as "G2 Compatible" might not be as a lot of the 'higher capacity' cells have identical dimensions.
Removing the Wrapper around the battery might assist with door bulge
If you feel like you have to aggressively 'wedge' the battery in then you might want to remove/modify the little nub's at the bottom of the battery near the contacts using nail clippers/dremel/knife. Otherwise you run the risk of damaging the cell-side charging contacts.
Some of the hardcore guys in here have sanded down the battery to have a good fit
The 'fit' differs from phone to phone depending both on the dimensions of each specific battery (not the actual brand or company, but each individual battery seems to be a little bit different) and the G2 Door.
If you leave the door bulging indefinitely it might damage the door in some way, it's recommended that you remove the door and just use a case if it's a major problem for you.
Tips:
- After installing the new battery, remember to reset the battery calibration through your recovery. This affects how many times you feel the need to "cycle it through" before achieving optimal battery life.
- Don't believe the temperature sensor on 3rd Party batteries
- Individual "Before and After" stories are cool, but not that useful considering all the variables involved with the hardware, the radio & signal, the software, and the human being (placebo affect). Aggregating all the data together does give us some picture of whats going on.
- The best tell for battery quality is the weight of the battery compared to your stock one, although this is not a guaranteed method.
Conclusion
After reading through as many threads as I could find regarding this topic, It seems that the CHICHITEC batteries have come to be the most popular across all these HTC phones. While the 1500mAh HTC EVO battery seems like the best deal with the most consistent power output.
The average perceived benefit using these batteries seems to be between 30-20%.

All Corrections Welcome, All Data Welcome!

Fantastic initiative. Unfortunately I only have the stock at the moment and I can't comment.
Did u mean Seidio or Sendio??

Thanks, this really is usefull and spares us who are still trying to figure out wich battery they want, alot of time!

For CHICHITEC 1800mAh battery, is it safe to shave off the piece allowing the battery to be a perfect fit? Such as trying to use a nail clipper and clip it off.

Very good work on compiling all this information.
All I wanted to do was add my experience. I went out on a limb and bought the 2000mAh batteries from Galilio.
I took the wrapper off and trimmed the tabs and have been using them for about 3 months now.
My battery door does have a slight bulge to it but I can live with it.
The other day I decided to go back to my factory battery because I now have a charger by my bed, one in my truck and one at work. I have to say, I am spoiled now. My G2 is loaded up and running like crazy and my factory battery lasted like 2 hours where my Galilio battery goes for about 9 to 10 hours.
I text ALOT and facebook runs all day, I use the navigation on a daily basis and play tons of games.
Hope my 2 cents helped.

CM 6.1.1 I absolutely love it. Tried the CM 7 but don't like it yet.

im on 10 hours of uncharge, so far its been light use, uncluding 1 hour and 30 min of GPS some texting, surfing and HTC updates

Thanks for compiling this info. I've had greatly improved life with the 1800mAh Mugen, but wasn't aware of the inconsistency some people are seeing.

Inspire 4G Batteries..

Thought I would start a battery thread just to see what everyone thinks. I have noticed the battery is 1230 mah and thats a little small for my taste. I have heard nothing bad about battery life, but thought I would start this thread to throw some options out there on where to buy hi-cap batteries. Also if anyone has experience with a site or certain make of battery, that is made for this phone POST IT UP. I haven't really been able to find anything.....

I guess I'll reply to the earliest thread.
You haven't heard anything bad about the battery? I have heard a whole bunch of bad things about the battery. I have also heard a whole bunch of decent things about the battery which leads me - and I'm sure many other android users - to believe that with SMART management and usage, there is no reason the battery shouldn't last one day.
If there was a proven extended battery greater than 1300mah on the market right now, I would have had one ordered and delivered to my doorstep already. However, because of the hardware design, this may prove difficult for manufacturers.
My plan is to get the phone, set it up, possibly root - and then evaluate if the battery is adequate - as many had said it is. If it is REALLY bad, I mean frustrating, leaving me stranded in a bad part of town with no cell phone... then I will return it.

Thats kind of what I had planned as well. I may also put a rom on it if they start coming out soon enough, because they have obviously shown to drastically improve battery on many many devices. BTW did find a couple batteries on ebay, up to 1600mah but obviously there is no way to tell if they are worth a dang or not.

They're not worth a dang from what I've read. Crap manufacturers label batteries as they'd like - good luck proving them wrong.
I'm looking out for a legitimate battery, not from ebay, that is over 1300mah. Will post if said battery is found.

I saw a review of the seidio "extended" capacity battery for the dhd and results were not very good. The battery is listed as a 1600mah, but it's true capacity was only about 85% of what it was rated. That percentage fluctuated as well and was some times as low as 70%. The HTC batteries while only being 1230mah were close to 95% of it's rated. So it seems that the stock batteries are the best choice.

well, I've read that the desire and inspire are basically the same phone, if that is the case than I know, personally, 4 people who own this battery and have said it adds about 2 hours of life with moderate to heavy usage.

I think you just pay them... it will convert US to pounds.
I ordered a pair of jeans from France this year and you paid as you would anything else... it just converts the euro into US and thats what it takes from your bank.

I would invest in extra chargers. I picked up an inspire today and that battery door is almost impossible to get off. It would be an act in frustration to try to change that battery even once! From what I have seen the battery is holding up pretty well. I crushed the phone for a few hours and downloaded about 20 apps on wifi. The level dropped of course but it held up better than my Nexus one is holding up these days.

^ That is one option I've used with good success. And the extrernal battery is just a USB connection so I can use it for lots of stuff. It recharges the internal battery at the same time, an added bonus.

I am thinking about switching to Inspire from HD2. Can anyone confirm that the Inspire 4g uses same batteries as HD2?

Do where can we buy the dhd batteries from?

I ordered a spare from an AT&T corporate store today. The receipt lists it as 1400mah. I assume it's going to be the stock 1230 though. We shall see in a few days.

2450 mAH Battery - Anyone tried this?

Just wondering if anyone has tried this battery. It's the newest one I've seen, and the highest capacity but, as we know, that may be bollocks.
http://www.ebay.co.uk/itm/2450mAh-H...ltDomain_3&hash=item53ea3aaba5#ht_2882wt_1144

i got it, the old battery lasted about 10 hours with me, this lasts about 12 hours under similar use... big difference is it takes about half the time to recharge! i think im gonna buy the Anker 1900mAh battery and try that out

The Anker 1900 seems to be the one everyone is using and actually IS 1900mAH. Some of these higher ones are false but I'd be interested in how you compare this and the Anker 1900. Going to get one of these anyway. Interesting about the re-charge time.

The recharge time is entirely possible of they punched a few thousand nano holes through the lithium to allow for the ions to transfer faster. However, considering the production time it probably takes and the price of this battery, I doubt it. I've been using the Anker 1900 mAh batteries and have been getting pretty solid life (with no calibration & heavy usage). I usually see 8-10 hours, which is fine because I just swap out the battery with the one that's been charging (I bought the 2-anker batteries + battery charger combo pack). I'm seeing some people say they get 20+ hours on a stock battery due to phone configuration? I'm not so sure about that yet. I'll do a calibrate, reconfigure my phone, then see what kind of hours i'm getting.

Mhh only 6 dollar. that is quit cheap. The anker 1000mAh costs around the double money and more.
Is it possible to built such a battery with _over_ 2400mAh with that money?
Just be careful.
Im using the anker one too. Really great.

I'm seriously getting a huge battery life right now, and I am on the Anker 1900. I have one battery but I have configured FauxClock to underclock the processor to 1GHz + I am using Juice defender on the Advanced setting. Yes the battery does need to be calibrated correctly but it's incredible the difference these two things make to battery life.
I use the phone a lot and I don't notice any lag when it's underclocked.

That is correct, I'm sure most of us spend a lot of time on the dev boards lurking, but in fact there is quite a bit you can do to make your battery life a lot longer without getting a new battery, aside from flashing a new rom and kernel. I personally have gone 20 hours with the stock battery, but that was with minimal use of course. One thing that increased my battery life significantly was making all my emails and updates C2DM, for instance. I'm sure there are a lot of users out there that still use email sync...

Here are my stats with ~10% remaining battery last night, before I went to sleep FB, LN, TW, Weather, 3x mail acc, all syncing as much as possible all the time, mails every 15mins, Whatsapp, Viber, GTalk, FBMessenger, ...
I'm super satissfied with this gold battery.

Anker 1600mAh in UK

One seller on UK eBay has the Anker 1600mAh DZ battery for £7.39 inc postage. That is a bargain price by anyone's standard, so I thought I would give it a try.I was half assuming that it would be poor quality or a knockoff etc.
Had it for a week now. First 3 or 4 charges I was very careful to charge fully overnight and then let it run down to at below 15% before plugging it in again. Full charge/discharge cycles are good for battery calibration and the good for the battery itself (apparently?!)
I have been trying out lots of different ICS betas recently and they have been chewing through my battery pretty quick. Also my stock battery is the one that came supplied with my DZ over a year ago so it was a little tired.
I always charge overnight. On my tired stock battery I would just about get through the working day and would likely need to plug in around 7:00 if I wanted to use/tinker with my phone in the evening. With the Anker I am easily getting through to the evening without going near a power point. So can get all the usage I need on a single overnight charge - perfect!
What I cannot comment on is what performance I would get from a new stock battery. Obviously it might be just as good or even better but for this price these Ankers do a very good job.
I've just ordered two more and a second replacement backplate. Guess I'm coming to terms with the fact the HTC are not going to release a high build quality, high spec, qwerty slider in the near future So we better stock up on spares/consumables whilst they are abundant and cheap

I just started using an Anker battery last week and so far it's working quite well. I've heard that non-oem batteries can lose their capacities faster so I intend to do a rigorous retest a year later.
I'd avoid buying up batteries for use in the future though. Lithium Ion batteries age with time as well and will lose capacity even without use.
For now though, it does seem to come close to the claimed capacity which was nice. I did some tests that were more controlled than simply using it for a day:
Code:
ILWT 285
1.5GHz Performance
Airplane Mode
Minimum brightness
MX Player SW Fast
Stretch Mute
Battery discharged to 89% before recharging back to 100% waiting for the trickle recharge to stop before starting video and unplugging.
Device running until 15% warning which is dismissed and then run until device auto shuts off.
Anker - Claimed 1600mah
375minutes
~250ma
1562mah
97.6%
HTC OEM 1300mah (1.5 years old)
274minutes
~250ma
1141mah
87.8%
I also ran another test with slightly different settings (which meant it couldn't be compared) where the average drain was 300ma:
319minutes
~300ma
1595mah
99.7%

Hi,
I recently bought the Anker 1600 and let AnTuTu Battery Tester run trough and got a Score of 630. In the AnTuTu Score Statistics it seems to be very good...
I am on Andromadus Beta3 (ICS) @1200Mhz
Don´t know what is this in comparision to the stock battery - I didn´t let the test run trough, maybe later. My stock batt is already over 1 yr old and I charged it almost every day or every 2nd day - so I don´t know if the result would be comparable...
Anyone knows about AnTuTu results of the stock battery?

you should test it with the exact rom, got 466 with andromadus on a new installation 768mhz, can't exactly remember other settings.
I'm seriously thinking of getting a new battery.
Anker doesn't need sanding or an extended battery cover, right? can't understand why the OP needed to buy a new one

No it fits fine with the original cover and is quite cheap as well - bought it at Amazon for abour 13 EUR including shipping. I think 466 is not so bad but I feel that Andromadus rom needs a lot of juice too.
With the new Anker I´ve got more or less the same duration like on cm 7.1 stable with stock battery...

Just got my anker in, excited. It fit perfectly, was @ 67% when I put it in, going to charge it all the way up and see what kind of results I can get with this badboy.
I don't know why but I'm going to trickle charge down to 75 then back up, then down to 50 then back up then let it roll. Me just being stupid.

After a couple of recharges now I think the Anker is even getting better - but I am not getting more than 4hrs "screen on" @Andromadus. But for a 10EUR battery not bad.

Hi guys
Could you guys please post here (or msg me) the ebay item number or seller name, etc for this Anker battery?? As even as a highly experienced ebayer with an account now for 11 years old, i find battery buying a complete minefield ........ sooooo many fakes that ebay take no action about.
So if am gonna try one of these, i'd at least like to get a genuine one.
Thanks

This is the one I bought yesterday:
http://www.ebay.co.uk/itm/220928813853
The seller gets good feedback from this and other forums and I'm pretty sure the batteries are genuine Anker. I believe it's the same seller as MaxWiz used as they were selling the same battery for £7.39 in February.
Can anyone please tell me how to get the best from a new battery? I hear different opinions on 'conditioning' batteries and do's and don'ts of charging/discharging.

Damn good service from the seller! Bought on the Sunday, dispatched on the Monday and arrived this morning. One working day as opposed to the advertised 5-7.
From the packaging, it looks genuine. The seller also uses Amazon marketplace which is probably why it came in Amazon packaging. Learned that 4-5 full charges and full discharges is the right way to treat a new battery so that's what I'll be doing.

I wouldn't fully discharge as its not good for it. Do a little more research, you'll find differing ways but the authorities on lithium ion batteries will tell you a full discharge is unhealthy

I wouldn't fully discharge as its not good for it. Do a little more research, you'll find differing ways but the authorities on lithium ion batteries will tell you a full discharge is unhealthy

Thank you
As you mention, I've seen a variety of methods, some quite elaborate. The manual that comes with the Anker battery says 4-5 full charges/discharges.
Based on your knowledge, at what percentage would you recommend plugging back the charger?

15 to 20%

Thanks, I'll do that.
I made the mistake of not charging it for several hours before letting it discharge. I unplugged when it got to 100% and let it drain to 84% before I read that the first charge should be several hours. I've plugged it back on charge again and will leave it overnight before unplugging. Hope I haven't knackered the battery

I'd also like to buy a battery, but it seems that the eBay seller from the link posted by Chem23 does not ship to Romania.
D'you have any recommendations as to what should I order, that ships to continental Europe (and Romania)?

Just like to say I love this battery. I can easily get 12-13 hours of heavy, heavy use with it. The best I've gone with intermitted heavy use is 22 hours. That is definitely a far cry from the 8 hrs maybe I would get with the stock battery.

The same seller sells via Amazon as LaptopMateUK. It may be worth looking at Amazon and checking if he can ship to Romania. Good luck!

Just got one of these, looking good so far, been very disappointed with the stock batterys inability to cope with all my tinkering and screen on time, hoping this will be the answer or at least a competent spare to keep in my wallet....

Checked Amazon but shipping is pretty expensive to Romania, higher that the battery itself... I'll check a few local stores, maybe one'll have this battery for sale.

I didn't find any other stores online where they send to the Europe mainland, and since i don't have a creditcard, I'm not able to buy on amazon. Anyone has any ideas where to get it instead?

Polarcell battery?

I am running an unofficial CM 10.1 ROM on my DHD and with 'slight' use I can probably get a full day out of the battery. Prior to the CM 10.1 ROM I was running a custom rooted ROM based on the final official android 2.3 ROM from HTC and I remember the battery lasting much longer (over 12-months ago). I won't be moving back to Gingerbread but want to improve my battery life and have seen good reports of the PolarCell batteries

Has anyone replaced their stock battery with one of these? Any comments?

Would be interested in knowing this also. Dont suppose you took the plunge and bought one?

Hi guys
I would be interested too on this question, or another battery brand.
Only want that someone with experience tell us if possible which battery and what brand/model is the best nowadays to buy to our great Desire HD?
And if you can post the link where to buy and maybe some buyer reviews, would be wonderfully.
Because are too many "Fake" vendors nowadays.
But for some questions that I asked to other few members and one recognized developer, they said that one of best batteries are:
First - Oem
Second - Mugen
Third - Anker
....
That PolarCell I never heard do not know =S
Cheers

I guess dhd battery is a pain in the a** for everybody, I suggest you to go for sensation xe, evo 3d type batteries. There are plenty of ways to do it (with battery door or without) I was personally using without battery door because I was already using silicon cover for all phone. Btw you need to apply a small copper wire for external wireless antenna which is already built-in with your original battery door. Search for thread in this section you will find Evo3d battery thread. I have changed to HOX but still my wife is using my beloved DHD with 1950mah Mugen. Believe me it gives equal amount of satisfaction for this money. If you don't want to spend that amount, go for original Amaze 4g battery (which has the highest capacity when compare with evo 3d if I don't remember wrong) still you will be satisfied with battery life.
Please don't ask me, which rom am I using or how is battery life. It depends on people and how they are using.
I can give several examples, heavy usage with all the time 3g, bluetooth, mail sync, whatsapp, viber, browsing, auto brightness but no games and no wireless: it will handle 1.5 day.
or
Moderate usage, all the time mobile network on, a bit whatsapp, several regular calls, a bit browsing, no gaming and wireless off. My wife can easily manage for 2.5 days.
One more thing, if you will have 1950 mugen, your battery will stuck at %15, don't panic it will stay there for at least several hours (according to your usage ofc). Its some kind of a bug. I don't know if somebody found a solution.
I hope, my reply will enlighten you a bit Cheers!

Been using a Polarcell since october 2012 from the manufacturer CellePhone: (http://www.amazon.de/gp/product/B004I227RK)
New, it lasts the same as the original for me, that means about 3 hours of screen on with about the 70% of the total battery time, automatic brightness but mainly outdoors, so I bet that the auto brightness is actually full brightness the most part of the time, using 3G and no "data sync demanding apps running in background" except whatsapp and the usual google services.
I use to charge the battery every night while I sleep and even though I'm aware that overcharging a long time is harmful I use to let it charge until I wake the next morning.
With this usage schema, I'm facing today a 20% loss approximately, because the battery skips from 80% to 100% when charging.
So is more than a year of usage, around 400 charge cycles, and for 10€ is a good investment for me.
Being from a german company inspires more confidence than chinese clones.
Hope this helps to all of you folks!

A friend of mine picked one up and he had nothing but good things to say. I'll update this post once he replies to my text for exact details!

Bought one a few days ago from http://www.ebay.de/usr/wannsee-electronic (Germany).
The one i bought is for HTC Sensation, sold as 1800 mAh. To fit in DHD i remove the "film" and im surprising to see that on the aluminiumcase of the accu is written 1700 mAh.
Contact the merchant today and wait for an answer. So I didn't know it depends on Polarcell or the reseller...

I just got one myself for Desire S, it is a 1600mAh battery. Been using it for 3 days and I'm quite satisfied with this product.. I also bought one Anker battery for Desire HD....
I can't really compare those cuz its on a different device and different ROM. But I feel that both are doing fine for now..... You can give it a try.
Btw, Anker battery comes with full package, it comes with a box and manual.... The polarcell that I received just comes with a battery with no box, nothing else..
Maybe I would suggest you to get Anker.

Don't forget to use Battery Monitor Widget to see if its actualy a good battery.

I got one today for my old DHD.After couple days of usage I'll post and my opinions.

I'm very satisfy from this battery.After couple charges for 12 hours each now my battery seems very stable. I'm running 30 hours and more with enabled 3g all the time.30-40 minutes calls including viber and 2 hours and a half display on.I think that this is a very gods result for this product.....cost 13€ .
