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.

I would say that the Mugen 1800 performs like a 1400 is an exaggeration.

[REVIEW] 1600mah batteries and charger

This is a quick little review of some 1600mah extended batteries for the desire HD. thees batteries where bought off of ebay from 2 different sellers, but both seem to be the same quaility and same manufacturer.
first of all, you can get these here
2x 1600mah extended battery with charger - LINK
1x 1600mah extended battery - LINK
So now for a bit of a review...
2x batteries and charger. - both batteries arrived relatively quickly, in a padded envolope. with there free shipping it was a little bit less than a week. came it great condition.
1x battery - paid $5 extra for expedited shipping, arrived in 2 days. works perfectly
Battery performance - all of the batteries have around the same performance. the ones with the charger have slightly less battery life but it is still better than the stock 1230mah. i can now easily go a full day of browsing the web and playing games without recharging. although, i dont like my batteries getting too low, cuz i know if they fully discharge it can be bad for them so at 20% i swap the one ive been using for one that ive charged overnight. the way i have it set up, i always will hae a battery fully charged. i have one in the phone and one in the charger overnight. wake up take both and put the other extended in the charger while i am gone. come back and before i go to sleep i swap again. they all get used equally then.
One problem that i have seen though, is that sometimes when i reboot or swap them out, when the phone starts up, it says there is 0% battery left. it is usually fixable by a quick wipe of the battery stats in recovery. has only happened to me in aosp roms though, sense runs fine.
overall, id give them a 4/5 rating because of the low cost and quality, but also because of that glitch(although it could just be software related)
pics up soon to show exact battery life and the batteries themselves

Okey n1 review. Perhaps i will get one of those batteries hate to charge all the time

I would love to see some stats/screenshots of Battery Monitor Widget just so that we can see what you mean by saying that you are browsing and playing games all day.
When i'm using my phone with the screen on all the time then i've got a drain of 1% per 5 minutes. That gives me a bit more than 8 hours before the phone is dead.
On the other hand the maximum standby time is a bit more than 100 hours (1% per 60 minutes) or more than 4 days.
That said you could have really great battery life if you've got more than 2.5 hours of screen on time in one day or it's terrible because the screen on time is way below 2.5 hours.
That's allways based on the assumption that your battery is depleted after 24 hours. "a full day" could also be a work day meaning unplugged at 6 am and recharching at 6 pm.
/edit:
about that 0% glitch: I'm using an Evo3D Anker 1900mAh battery in my DHD and got the same problem. I also think that it's related to me using an aosp rom.

I actually have this one!!! ordered from dealextreme.com!
its working fine 1230 mah real size! there is no bigger batteris than 1300 mah!

There IS a battery that is more than 1300mAh, the Mugen 1500mAh. Search for it on this forum
There is also the Mugen skin that clips on and holds another 2000?mAh, but that is not entirely practical...

That's why you should stuff an Evo3D/Sensation battery in there
Those have 1500mAh or more (and really do!)

These batteries do hold more juice than the stock. I don't know why people are complaining about them. For $9 you get 2 batteries and a charger. Even if they where only the stock size, you can still swap them.

Problem is, these claims have no substance without numbers. Do you have any test results proving the battery life is greater over stock?

anyway:
it doesn't matter if your phone isn't on for some time....just let Battery Monitor Widget run from 100% to 0% and then show us screenshots of the stats it gathered.
Thoughts about how well your batteries performed aren't needed. I bet you i could give you the exact same thoughts you have about your batteries only that the time from 100% to 0% differs by as much as a day....

Battery Monitor Widget:
It's in german so this is what it says in english:
(in the info bar at the top you can see that i had still got 31% charge)
- has been unplugged for 1 day and 2 hours
- has been used for 5h20m or 20%
- screen was on for 2h31m or 9%
- wifi was on for 2h03m or 7%
- bluetooth was on for 1h32m or 5%
It doesn't say anything about how much the gpu was used (for example there is no reliable way of telling how much the usage of opengl drains your battery...at least as far as i know).
But it still gives you better info about how i used my phone and how much you'd get if you were using the same battery.

What about this battery?

Hi all.I really need to buy a big battery for my sensation and i found this battery .Anybody know something about this battery? Or i must buy a XE stock battery?I`m from Romania and there not found Anker battery and nobody deliver to Romania.Thanks!

If you are willing to take a risk, it could pay off or it could not. If you aren't able to get the Anker battery and don't want to take a risk, I would say go with the stock battery.

You won't risk anything with the XE battery. I had misread that and thought you were going to buy the 1520mAh stock one instead of the XE.

I bought my replacement battery from dx.com and seemingly hit a lucky strike: it's supposed to be 1700mah, yet measures over 2000 in Android Tuner. Cheap, free shipping, pretty much ideal except for the ~3 week shipping time. Doesn't get especially warm, works perfectly, and capacity has only gone up in he couple of months that I've had it.

Hi.This results is after a low using of phone (5-7 min of facebook,few calls/sms and 5 min of gaming).Can see in the photo.I have perfect deep sleep but when i use phone battery drain a lot.Especially in games(5-10 min of gaming = 20-30% ).I have these settings:vipers rom v1.6.3 + faux kernel with intellidemand max cpu 1188,min 192,max screen off 486 and UV -50.

I really don't know - I'd guess an original replacement has somewhat better quality, but I'm not really finding anything wrong with this battery. The only niggle I have is that remaining battery capacity changes on reboots - it might say I have 30% left before rebooting, and then 40% after (I just made those numbers up, but they're pretty representative). It always goes up, though, so I never have less battery remaining than what I'm seeing. I'm guessing this might have something to do with the battery not reporting its actual capacity to the phone (from reading other threads, only original HTC batteries seem to do this), which maybe means the system has to calculate remaining capacity from other factors(?). Still, it doesn't really affect anything.
I've attached a few screenshots I just took, showing some stats and my current usage (as you can see, the phone has been pretty much constantly in use today, mainly web browsing, but some text editing and other stuff too. Always multitasking, several tabs in the browser, and so on. Wifi on all the time, auto brightness, syncing 2 google accounts.). It's currently running at 1728MHz, Badass @performance (918/1188/1728MHz), with [email protected] 320MHz 3D, 266MHz 2D.

Yeah, I had the same problem - after a year and a few months my battery never lasted a workday even with light use, gaming could drain 30-40% in a matter of minutes, and it got ridiculously hot. I also got random reboots all the time. I concluded that the cheapest fix to try would be a replacement battery, and this solved all my problems
If you can get the stock XE battery at $18 including shipping I'd say that's a bargain, and you should probably go for it. Still, the Pisen battery is ridiculously cheap (and shipping from DX is free, if slow). If you can afford it, i'd buy both, try them out, and keep the least good one as a spare. Never know when you need one

[Q] Battery Life

Are you sure 8 hours are too few? It depends on what you do in those 8 hours. Try to be more precise about your pattern of usage.

I do use it quite a lot, it's just I'd like a bit more. I've tried reducing the screen brightness and slowing the cpu but maybe the answer for me is to not use it so much.

Yep, autobrightness and google location service (or what else is named) are two major things to work on for battery life. I don't think you should downclock the cpu instead.
Let's say if you browse the web for half the time (4,5 hours) it's normal.

Web browsing will eat battery. My phone is used for work and it's on a 2g only signal, I can be on the phone for an hour or more each day and the phone will last two days easily though I always charge it overnight anyway.
Maybe one solution for you is to buy a battery pack to recharge it if you can't be near a socket or possibly even one of those powerskin (not sure of the name) cases that have a battery in them.

I will look at the Powerskin, thanks. When I had a Wildfire I just used to carry a spare battery, which I can't do now. I have a charger with me to grab a bit of charge when I can, so perhaps I'm not doing too bad considering how much I use it.

You may also want to search the thread about battery replacement with One X+ (2100mAh if I'm not mistaken).

Thanks will do.

best battery option without adding bulk

I was wondering if anyone can recommend to me a good extended battery that doesn't add bulk or the requirement of a special backplate to the s4?
I don't seem to have as much success as most people here on the phone with battery life, and if i'm lucky I make it to 3 hrs screen on time on each battery (I carry around spare batteries but this is still annoying).
Appreciate the recommendations

I don't believe there are any options for extended battery without bulk. You could do the zerolemon 3000 mah batteries. You get two of those and then you could always have a spare battery ready to swap when the other one dies. Other than that, you're going to add bulk if you want an extended battery.

I would advise you not to use batteries by this brand. I've opened up an extended battery they made for the i9300 and discovered that they use spacers to add weight to the batteries instead of using two batteries like the reputable brands(anker,hyperion, zerolemon). The closest you would get to an extended battery is the 3000mah zerolemon.

The battery arrived today and I am giving it the first charge. I will see how it goes and report. I hope it does not mess up my device ...
So far I am using it for 30-40 minutes and it is charging and charge progress seems normal and the temperature also.
I will be back after a couple of days to share the whole experience

I was wondering if anyone can recommend to me a good extended battery that doesn't add bulk or the requirement of a special backplate to the s4?
I don't seem to have as much success as most people here on the phone with battery life, and if i'm lucky I make it to 3 hrs screen on time on each battery (I carry around spare batteries but this is still annoying).
Appreciate the recommendations

Would like to know how it performs as well
If its got a 2 year performance warranty they must be pretty confident in it

On their site it says i9500 ,does it work with i9505 and it fits on original back case ? I would buy it instantly if i could get over 4+hrs on screen with stock rom my max with stock rom is 3.5 but awerage is 3hrs.

It depends on your screen brightness. I am using an 100% stock rom. I get on a full day around 5 hours screen on time with my brightness ranging from 0% to up to 20%.
I also tried this, use the phone with the brightness set to 0%. I managed a staggering 1 hour screen on time while just losing 15% (was whatsapping for an hour).
I don't like the stock battery life as I have to recharge my phone twice a day.... I usually go leave the house at 7AM and come back at around 6PM with around 10% left. Then, I charge it fully and by time I go to bed, the phone already has lost around 40% battery (I use the speaker alot and download Torrents). Then I start chatting with friends in bed and go to sleep with around 10-20% left on the same day (although that's at around 2AM). Thus, even with my battery life, I can't make a full day.
Although I must say, I am a heavy user. I use whatsapp, browser, music player, snapchat, facebook and the camera to take pictures alot on a daily basis. I use my phone with the lowest brightness possible as long as I can see what's on the screen to prolong the battery life.

@hare899500 and 9505 has the same battery

As far as the battery issue, not much you can do.
Try another rom!
I'm on latest crash rom and look

Sorry I didn't get back sooner.
I use the Opteka exclusively and am able to get a full day, but it depends on how you use your phone.
They don't advertise a huge upgrade, it's only marginal. you will not get anything above ~2800-3000mAh to fit inside the existing back cover.
That being said, I have yet to have any issue with the Opteka brand.
They also make camera batteries and accessories.

So you think it is better than stock?
Going to replace my original at some point. I never really have issues, though. But they are so cheap I might as well do it before it starts to become a problem, I only go above an hour or two of screen time when I travel by air (can't imaging spending 20%+ of my waking life looking at a 5" screen...don't know how you guys can stand it, lol).

i have polarcell 2900mAh battery for about 2 months, and I am really pleased with it.
Ok, I dont have stock rom, but compared to stock battery it gave me a great results.
About 35 hours without charge, and 2h 40min screen on

Good luck with this one. Most ebay battery is faking the capacity, if the size is just same as the original battery, there is no way it can be 3000mah, u can't beat the physics law.
But I just got another ZNC battery from amazon for $3.99 for a deal [I'm a new user, can't post the link here, if you guys interested, can search 'ZNC battery' at amazon to get the deal]. I have been using it for 3 days from now, works great so far and last just like the original one. I'll report it back this weekend, if I got time for the capacity test.
