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.

Add the DX batteries.

Battery options: Extended vs. Spare regular battery

Like many thunderbolt owners, I'm slightly annoyed with the battery life.
Is it worth the bulk and cost ($45) to get the extended battery when I can just get a $15 spare battery? The regular battery fits in my wallet. I know a droid X owner who carries a "wallet battery" as a backup.
PS- is there a standalone battery charger for the regular thunderbolt battery?

I went for the extended. Yes, it's bulky but it also makes it through a long day of heavy use without a problem. Plus, that battery door is so hard to remove that I'd rather not mess with it.

The extended battery will certainly do the job, but it adds bulk & weight to a phone that's already no lightweight. And the case selection is pretty limited too. You can get a spare battery + charger for ~$20 on ebay. I can give you a link to a reputable ebay seller if you're interested.

Keep in mind that if you're using a spare battery, it means the phone has to power down, and unless you literally run it to the point of shutdown you aren't going to literally be squeezing every bit of power out of it. You'll get more total time with a 2x capacity battery than a spare.

I would say go with the extended. I only charge mine overnight and it makes it through a full day (5am-11pm). I do turn off 4g when I am at work and when not using my phone however.

A while back I got a 3-pack + charger on ebay for about $20. I haven't had any problems with them. I haven't noticed them lasting less than the original. Either way, I have 3...1 stays in the office, one in my backpack, and one at home.
It does suck taking the case & cover off (the case that I had on my Eris came off faster than a prostitute's panties). I usually have it plugged in for my commute so the battery makes it, and I really only swap batteries on weekends, especially when flashing a buncha ROMs.

I went with these. They are a little more power than stock 1700mah and you get 2 batteries plus wall charger for $34.99. They work very well for me and get me 2-3 hours more time than stock with moderate use...
http://www.htcexpress.com/search?or...search_query=thunderbolt&submit_search=Search

I tried the extended batter and I did not particularly like the weight and especially the bulk of it. It just isn't for me. I have home, work and car chargers, so I can keep it charged when I need to.

Do the 1700 mAh batteries fit under the stock cover like the 1600's do?

i went with the 2750 mah and love it. battery lasts 14 hrs (no 4g coverage where i live) i got used to the heft rather quickly and love it. now to mod the car dock to fit this thing.

I have a spare standard battery and an external battery charger. Works great. I charge both up every night and keep one in my pocket. Haven't run out of power yet, and I'm pushing the phone pretty hard. (Live wallpaper, oc to 1.5, gps always on, 3g, sync, lots of texting)

I'm really pleased with the extended battery from Verizon. I just left the phone running to see how long it would go and I've gotten 2 full days out of it. It's been running 34 hours now and I'm at 5% power. I'm running bamf 1.7 and I'm in a 4g area. Although most of my time is spent on wifi.
I find that the phone is easier to hold with the extended battery. And the back is hard to remove so it's easier not having to worry about changing the battery.
I picked up 3 - 1500MAh + charger from ebay for $11.34. Link Here
I got the batteries in less than 2 weeks and I had a friend order from the same place and he got his fast as well. I've found these batteries as good if not better than the stock battery.

I bought that same 3 pack on ebay. I keep a spare one in my wallet. Works fine

I've been debating ever since I got my phone two weeks ago if I was going to give in and get the extended battery or pick up a cheap spare regular battery+wall charger and hope somebody will come out with an extended slim battery.
That link posted for the 3 batteries and charger for less than $12 seems like a good deal. I think I'll end up doing that so I can have a battery to carry on me and I can give one to my girlfriend.

I bought both the extended battery and the 1700mah batteries. I only used the 1700mah batteries like a week and got annoyed by the battery changes and bought the extended. Been happy ever since.

I bought from this seller. He is in New York, if I remember correctly. If you are in the continental US, you will get your items within a week.

I ended up going with the Verizon Extended battery and also got the High Gloss case for it too.. Now its complete in my eyes. I got used to the phone being this size now. Not bad at all considering how long the battery lasts now. It rocks.

I would say that you should first install Juice defender free. You will see that your battery life is greatly extended. You don't need root for this, it's an easy install from the market. After that, if your battery life is not acceptable (mine is), then go buy something

Battery suggestions?

I'm planning on buying a higher capacity batter for my DHD: any suggestions? I don't want a bulky external battery, the thing is big enough as it is.
I found this on eBay, but it seems waaay too good to be true.. Is there a risk of it exploding in my pocket, or just of it being really crappy?
Are the Mugen (1500mAh) or Andida (1800mAh) batteries any good?
Any answers will be appreciated
Thanks

From what I've read, the Mugen batteries are good but they don't make too much of a difference in normal usage. I really doubt there can be such a huge jump in mAh without any increase in size as the two batteries suggest. 1500 mAh seems plausible, but 1800 mAh seems very unlikely. The actual capacity will be much less than advertised, hence the not so great performance improvement.
In my opinion, (if you haven't done this already) you'd be better off rooting your phone and installing one of many custom ROMs here which give excellent battery life over the stock ROM. I get around 18 hours of moderate to heavy usage and more than a day of light usage. Also, I keep 2 standard batteries. The battery life offered by that combination is much better than a single higher capacity battery, and the HTC battery costs a lot less too.

I want a higher capacity battery also! any one have suggestions?

Thanks for your answer I might go for the spare battery, even though I probably won't ever have it on me when I actually need it
As you can see from my sig, I have installed RCMix's latest custom ROM, but while it adds lots of great features, my battery life is actually shorter than with stock.

Yeah I tried RCMix3d Runny 4.0 and found the battery life quite bad too. Even with killersloth's UV scripts and all that. That and average GPS performance (~6 satellites usually, weak lock) were the only problems with it. The RCTweaks are awesome.
For the best battery life and fast GPS lock (~10 satellites strong lock), from my trials, I've found that these ROMs give the best performance -

If you're going to buy a replacement battery, get an OEM one (0% improvement over stock ) or get the Mugen 1500mAh - that may just get you through to the end of the day.
Definitely, install a different ROM, and look at the clockspeed options you're given (or just install OC/UV Beater) You can overclock or underclock, and also play with undervolting, which improves efficiency.
Also consider network management, screen brightness etc -an easy way to do so is to use Juice Defender, though the purists say all their options can be effected manually.
And if all else fails, you can carry a battery pack around http://www.amazon.co.uk/New-Trent-D...1OK4/ref=sr_1_3?ie=UTF8&qid=1326811038&sr=8-3 this is 5000mAh, these people produce an 11000mAh version. My 5000mAh pack is great for sticking in the rucksack on a long day out with GPS enabled, cost about GBP20 - of all the options I evaluated, this is best value for money - also no need to switch phone off, vs changing the battery). Their customer service was very responsive when I told them that the charging cable wasn't working

Don´t waste your money in chinese batteries.I tried a few myself.If you really need it,the best thing is to buy anther OEM one.

Mugen's 1500 battery shows about 15% better capacity than my almost year-old stock one (1270 vs. 1095mAh, as measured by the battery monitor widget, after its first 4 cycles). Does not look quite like 1500mAh, but I guess the stock one never did register 1320mAh in that measurement either - it's either a systematic error, residual change or something...

The original htc sensation battery has 1520mAh and costs a lot less than the one from mugen. And i'd say you can trust original htc batteries more than anything found on ebay

I have an (china) battery from ebay with 1600 mAh. the battery life on our phones is really really poor. I heavily used my phone of the day an i only get a battery life from 6-8 hours, and thats really bad. So i found that no battery is even better than the original.

Though Mugen is not a perfect solution, it is better than stock batt.
Don't just go for price when you are buying batteries too, especially those dirt cheap china batteries. I bought a few before, it bloated up after a few months of usage.

hi, can some one suggest me(I am heavy user) witch is the best battery for DHD and best place to buy ?
Thanks

Due to DHD specialty, there can be used batteries with the capacity not more than 1500 mAh. All the numbers more than 1500 are either lie, or mean that battery is thicker than DHD body can support.

That's why you've got three options:
1) use multiple batteries (not really an option)
2) use an external charger (better, but i don't want to carry around more than the phone)
3) if you use a protective case then get a sensation battery....mines got 1900mAh and fits nicely into my DHD

You can also use a secour / external battery .You can reload four or five time you phon whit.

I have one extra 1230mAh battery & an Energizer XP2000 Portable charger. But to my opinion, adjusting your phone-charging habits makes all the difference. Anticipate with respect to your day's routine.
Though, I'm looking forward for the GSM version of Motorola Droid Maxx, or for any other that rivals its battery capacity.
p.s. charging extra batteries individual would be nice. I should try modding some usb cable to connect directly to the battery contacts, hmmmm...

1500mah "OEM" Battery?

Has anyone purchased one of these so-called OEM batteries?
http://www.ebay.ca/itm/OEM-1500mAh-...141606?pt=PDA_Accessories&hash=item255ecad726
This one claims to be a Desire Z OEM battery rated at 1500mah. Isn't the OEM battery only 1300mah or was there another one that was released?
Also, has anyone any luck with the 3500mah ebay extended batteries? How are the doors and are they at least 2600mah?
http://www.ebay.ca/itm/3500mAh-Exte...863751?pt=PDA_Accessories&hash=item5642245107

Yeah, I see on T-Mobile's website, the G2 also has 1300mAh. I wouldn't recommend buying a third party battery though, just watch this video about a PSP having a third party battery.
http://www.gametrailers.com/user-movie/psp-explodes-in-pocket/172723

It's a matter of buying a good, name brand battery. 3rd party or OEM doesn't matter if it's a good quality and the listed mAh rating is accurate. You get what you pay for 90% of the time...

eBay is filled with counterfeits, and lots of items marked "OEM" when they aren't OEM. I'd stay away from buying things like batteries and SD memory from eBay, unless you know for fact the seller is offering legit goods.
The pic looks hokey, also. It looks like a stick-on label, instead of the screen printing I've see on HTC OEM batteries. I'd be willing to bet this is a knockoff, misrepresented by seller, etc.

I can vouche for HTCpedia having purchased several extended batteries from there myself
Here's there Desire Z section
http://shop.htcpedia.com/htc-desire-z/accessories/batteries.html

I recently purchased the Anker, I believe, 1600mah from amazon. Battery life is better than the OEM.

I would personally stick with the stock 1300mah battery, and UC the cpu to save battery life. Unless your original battery has gone bad and you need to replace it altogether. I'm always weary about 3rd party accessories.

The Incredible S has a 1500mah battery that's the same size. I'm not sure where to get one in Canada though (can anyone enlighten me?).
For that matter, if the Anker is available in Canada I'd be interested in knowing where too.

Based on the price for the battery listed, this may be a little out of your range, but I picked up this one on Amazon:
http://www.amazon.com/gp/product/B004M8RWLG
And it really picked up the slack from the 1300mah OEM battery, and still fits under the stock battery cover
HTH

Battery life on my G2, even when overclocked to 1512Mhz on the stock CM kernel, is pretty good. HTC has been really slacking off with battery life lately *coughDOUBLESHOTcough*.

Well, I've received my Anker 1600mah battery.
Since it doesn't claim the world, I'm thinking it might actually be true (unlike the Seidio or Mugen "1900mah" batteries that end up only 1300mah).
Even if it's just 1300mah, the price is right =)

Can you post any "Better battery stats" logs or verify how much capacity it actually has?

Interestingly enough, I have some records from the tests I've been running this weekend. This battery has been surprisingly decent considering I only expected 1300mah (from the advertised 1600mah) out of it.
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%
The test is as consistent as I could make it since I only have my phone to discharge the battery with.
With that said, I have heard some non-OEM batteries lose their capacities faster than the OEM ones. I plan to do this test again at the 1 year mark.

I haven't tried those "OEM" batteries before but I've heard a lot of good reports on the "MUGEN" ones. Supposedly, if you follow the instructions, it'll function as it's suppose to (meaning it'll last long).

I'd recommend anyone looking for a extended battery to get a EVO Design 4G battery! It fits in our device perfectly at 1520 mah A BIG JUMP from our 1300 mah stock oem batteries.
Most if not all 'after market' batteries die out quicker and don't live up to the battery life that there claiming to. . .

Aftermarket Batteries

has anyone tried any of the aftermarket batteries, whether it be from a store, ebay, amazon, etc.
I ordered a 2200mah battery for my Infuse off ebay for $8.
I am going to try that out and see if I get anymore life out of it.
I would have gotten the 3500mah battery, but I use an otterbox and I dont think it would fit since it has the bigger cover to hold the bigger battery.
I work in a metal forging plant, so I have to use an otterbox for my work... so it is a must have if I want my phone to last.
I did order a 3500mah battery for my wifes Samsung Captivate.. She doesn't really use/need a case. I got that off ebay as well.. for about the same price.
I hope her phone lasts longer, because she can't even get a day out of it... hers is rooted running MIUI.

I just got one of them 3500 batteries from amazon and its a solid battery, it wont fit on the case because i have the Otterbox case and cant use it with this, but you can definitely tell the difference in how long it lasts, and the case fits on the back of the phone great it has tabs and snaps right in. I use this battery when i am at home using wifi or alot of power on my phone and use the Samsung battery when i leave. Great investment for $10 but when you have the case on the phone it won't do you no good.

Getting a larger battery will help, but there's a lot of ways you can manage your phone's power consumption to dramatically increase your battery's life.
Take a look here:

All I've done is use the power management program Juice Defender (on extreme setting, so data is off unless I toggle it on), not use a live wallpaper, and use a Gingerbread ROM (R3VELATION). With light to moderate use I get about a day of life, and if I took further steps I could even get more out of my battery than that.
EDIT: Whoops, you're the same poster as here, so it looks like the new larger capacity battery has solved your battery problems. I'll just leave this post up here anyway since it might help others.

Would the bigger battery cause it to overheat? or damage the phone in anyway?

Bought the two pack of 1800 batteries from Anker at Amazon. they work drivers. I no longer have my phone plugged in as I can just charge all of the batteries using their awesome wall charger and such one in when a battery dies.

I also recommend to use dock charger like on ebay, i bought also 2200mAh batterys so i can charge them both and the free one can charge much faster since it's not in take-and-give cycle like when it's in phone usage.

Came in here to ask the same question about aftermarket batteries...was thinking about buying the OEM one off ATT site for $30 because I don't see an official aftermarket battery and i'm not sure I want to buy a $10 aftermarket off of amazon or ebay because of stories I hear about cheap China made batteries exploding or damaging the phone in some way
I just placed an order for this.....
http://www.amazon.com/Samsung-SGH-i...BMJ8/ref=sr_1_2?ie=UTF8&qid=1332809949&sr=8-2
The description doesn't say so but all the reviews say it comes with an OEM battery along with the charger...great deal for $30 in my opinion if it is all OEM

The thing I've read about these batteries is they don't have a shelf life. Meaning as soon as they are made they start to depreciate. Then they sell the old ones on e bay, amazon at reduced prices as they don't last as long as a freshly hot off the press battery.
I have never had any luck in buying a extra mha rating battery, having it last an extra long time. I got Chinese 2500mah it don't last that long, and then I went and got a high capacity gold 2430mah it only last as long as a 1750mah , rather I have no idea how long normal is, as I got my infuse at a pawn shop used, battery last about 5-6 hours, normal usage, but what is normal? What is the basis of comparison? I mostly use it for movies, and wifi and, angry birds which eat my battery up.
My theory is the more you pay the younger they are, a 4 dollar batter last less then a 10th dollar battery. But I don't have the monies to buy every battery in all the price ranges to test and do all that techy stuff. To me it is just a grip shoot. Hit or miss.

can't learn how to fix it, if you don't break it first

All batteries age during use.
Aging factors are temperature and also voltage.
I think temperature is well known but I don't hear as many people talk about voltage.
Charging your phone to 100% and leaving it on the charger encourages aging.
Some of the cheapo's are not as resistant to aging as the stock batteries. Common story is they work fine for the first day or two and then start to noticeably lose capacity. I noticed that when I tried out the Fujei battery.
Adding to the whole mess as you alluded... evaluating battery life quantitatively is not an easy deal. My usage varies every day.
I get a rough feeling when my battery life is fading but it's subtle.
Battery Monitor Widget has a feature where it estimates your actual 100% battery capacity in milli-Amp-hours (1750 = factory spec but actual will be different and will decrease over time as the battery ages). I think that if you use BMW and allow your phone an uninterrupted charge from low voltage like 20% up to 100% (without using the phone during that period), then it will develop a pretty good estimate of your battery 100% milli-amp-hour capacity (because our phone does have a charging current monitor which BMW accesses, but it does not have a battery discharge current monitor). That's a lot of work, but probably not a bad thing to do once a month to keep track of your capacity so you'd see a trend like 1750 one month, 1700 the next month, etc. I might start doing that some day..

3500mAh Battery
It's been a week, and my battery life is going UP. I plugged in today, and at 1931 hrs today, I still had 61% of my battery life left. I have not had any appreciable decline in battery life, nor reduction in longivity. With the stock battery, my phone is completely dead by 1715. I unplug daily at 0800. My battery life has easily doubled by purchasing a no-name battery from an Ebay seller. I'm quite impressed with it, and I spent $80 on an extended battery when I had my TP2.

Has anyone try those 2500 mah batteries from ebay? I am interest in buying those since they are only 4 USD each. What do you guys think?
