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

Battery problems?

I've had this phone for a while, and i just haven't been using it the past, ohh year? I tried a while back to fix it, and I know it's something to do with my phone/it's battery, It can stay in standby for about 26 hours, (no wifi, no sim card), but any phone call or wifi use lasting over ~5 minutes and the phone dies, but the phone reports that it still has about 30% battery left as it's shutting off!
Is it possible my phone isnt allowing my battery to charge fully?
I remember reading somewhere about the phone storing battery stats? I wanted to give fixing my battery one last try before I break down and order a new one :/
it's running CyanogenMod-4.2.15.1 (firmware 1.6)
so it has whatever ancient recovery comes with that, I would upgrade my phone but I don't trust it not to die during a flash and brick it.
To sum up the wall of text, my battery is dying from 80% in <5 minutes when not plugged in, and it dies when it says it has approx 20% battery left.
The battery is also sort of bulgey, perhaps, it's like 5/4 the size it should be? 9/8? , it makes a tiny bit of a bulge appear on the keyboard too.
Edit:
The recover has a green carebear with a nexus one logo on his (her?) tummy. RA-dream-v1.6.2

Same problem on official 1.6 rom + root. Battery or charging problem?

Certifiably battery here, i tried with my dad's battery and it seems okay, but i'm not entirely sure because i didnt have my sim card in it to test its usage lifespan

My G1 has terrible battery life, even when I'm not using it, I think the best solution is to buy a new battery

Yes I'm agree with AndyFox2011 view.Purchase a new battery .

Hm. SHould i get this battery:
http://www.amazon.com/Li-lon-Battery-HTC-G1-Google/dp/B001ZTZ92E/ref=pd_bxgy_cps_img_c
Or this one:
http://www.amazon.com/Extended-Capa..._1_2?s=wireless&ie=UTF8&qid=1316633929&sr=1-2
or this one?I've heard more about this one than others I'm hesitant though, because i love having the hard cases on my phone, and i'm not sure it would fit
http://www.amazon.com/Seidio-Innoce..._1_3?s=wireless&ie=UTF8&qid=1316634086&sr=1-3
or is there another low cost ($20 or less) battery that you would recommend?

I'm no expert, but I'd go for one of the extended batteries, they'll last a,bit longer than a normal one

X10 battery drain solved - by buying a new battery

So I always assumed the battery drain was a hardware or software issue, especially as my X10 would often shut down on 40% power and refuse to stay turned on unless the battery were taken out for 5 minutes.
Rather than buy a new phone I thought I'd try a new battery (I have had the phone since August 2010) - just £3 from ebay, and since then my battery life has been astounding - I'm quite a heavy user, but would almost run out after 8-9 hours despite keeping everything off and only switching on 3g and wifi when necessary. Now I can leave wifi and 3g on all day, leave the phone at medium brightness setting and still have 40% after a 15 hour day of medium-heavy usage.
I used to get idle drain of 1% every 10-15 mins as well (unless the phone was rebooted), but that seems to have disappeared as well.
So before you give up on it, do try a new battery, especially if you've had yours over a year. If there's no effect, you've lost £3 and still have a spare on hand.

Hello friend,could you please post the link where did you buy?

You think people on here throw their phone away because of battery drain,and it doesnt cross their minds to buy a new battery.....instead of buying a new phone.
I just hope your £3 battery doesnt damage your phone........or explode when youve got the phone in your pocket.......or during a call

Whats the size? i have a 1500mAh and a 2600mAh whats ur cpu settings also? looking for a good setup thanks in advance!
Also amazon link for 2600mAh btw its a big battery, and requires its own case which is rather bulky (http://www.amazon.co.uk/Sony-Ericss...TIMS/ref=sr_1_1?ie=UTF8&qid=1331594837&sr=8-1)
This is the 1500 i currently use, still getting the battery sorted with kernels ect
(http://www.amazon.co.uk/KC-Electron...1?s=electronics&ie=UTF8&qid=1331594882&sr=1-1)

I would just like to confirm what OP wrote. Not only did my new battery (I got the 1800mah one from Mugen, $33) solve my battery drain, it also solved my mysterious reboots, lockups, and heat issues. My phone would regularly get up to 48 celcius, it would result in it automatically shutting off the charging. It was a pain in the butt when using GPS on long trips as I would have to have the AC run straight onto the phone just so it would still charge. It was like this from new. With the new battery it has not budged above 29 celcius with GPS navigation, 100% screen, bluetooth, music and sync all running at the same time, I am shocked!
In order to condition the battery I turned off the screen timeout ("No screen off" in the Market) so I could get it to drain to 5%, it lasts twice as long even with the screen on all the time then it did before I got the battery, feels like a new phone.

beware of cheap batteries
beware of counterfeit batteries. Ive read a bit about cheap batteries being inferior knock offs. You tube has several vids about how to tell the difference

I'm about to buy bigger battery for my x10i. Now I have original 1500 mAh. Do you, who already tested thease 2500 mAh bateries see the difference?

My phone starting doing the exact same thing... shutting down at around 40% so I order the Mugen 1800mAH battery as well. Should get it in a few weeks... I did see much cheaper batteries available but figured you get what you pay for, and the reviews on the Mugen batteries seem to be good so I spend the extra money for it. Looking forward to the extended battery life!

[Q] Battery remains on 1% for almost one full day

I am creating this thread after exploring the options documented in other similar threads, where I have posted the same issue.
My original battery was weak and I got a new one for my Defy green lens.
I saw that the phone stays at 1% for a long time and then tried several of the tools which remove the battery stats and claim to re-calibrate the battery.
After several such cycles of full 100% charge and discharge till power-off, the phone's standby time has exceeded 2.5 days - out of which it remains at 1% for almost one full day.
Note: I am running Quarx's 4.4.4 nightly.
What are the other things I can try? The phone is used only as standby so I don't mind wiping it off completely and putting stock ROM and observe again.

Dont worry . this happens to me also.. im too bought a battery of 600rs from ebay and battery stays 1 % for a day...
For an investigation i checked the battery voltage (at 100% charge voltage will be 4.2) when it drops to 1%, its nearly 3.9 and phone will keep working till voltage reduces to 3.5... im getting 2 days minimum backup of moderate use...
now to explain why 1% , this is an answer i gt from FB group .. "dnt expect Original battery at 600rs wen its actually cost 1200rs, they are actually replica of real and the so battery circuit send false info to phone, and phone calculates percentage remaining on this "
i tried to switch some cm7 version but in all battery drop at 1% happens.... so i ignored it and my defy still rocks in daily usage after 3 years ...

I find it odd that this is not an original battery.
The battery charge is pretty good - more than 50 hours - no usage of the phone - but poor 2G connection/ weak signal.
I can contact the ebay vendor if that is the case, but I need to be sure first.
I have now put my original battery and I will see if it drains off in the same way or not.

I paid Rs. 600.
I put my original battery (3 year old) and that does not show the 1% issue, though the battery life is less than 2 days on it in standby mode.

Note 4 Battery Problems

Hi everyone!
I got a Note 4 a few days ago and it has battery issues.
I got it second hand online from a guy I don't know. I'm from Romania, I think the phone is from the UK, it's Verizon branded. The model is SM-N910V and the Android version is 6.0.1. It's not rooted. I noticed this V version isn't very common.
The battery that came with it was pretty poor, it would drain in a few hours with minimal usage and the worst problem is the phone would suddenly shut down at about 30-35% battery life. Then it would go into a booting loop, without being able to actually boot until I plugged it in.
I bought a new genuine battery from a popular online store here (F64), battery life is better, but still with just wifi, it went to 50% in about 2 hours of browsing. Without wifi or data (very little), it lasted for a day and a half. But the phone suddenly shut down at 8% battery life, again going into a booting loop, without being able to actually boot until I plugged it in. I'd also like to mention, when the new battery came, it only had 4% battery life left (I heard they should come about half charged, is that true?) and also there were a few reviews from people who had to try multiple batteries from this store until they got lucky with a good one. Both the old and the new batteries look identical, I don't see any signs of counterfeit.
Should I return the battery and try a new one? Is there a chance there's something wrong with the device itself?
Thank you very much!

Common problem.

Return the battery.
The seller store the battery in a very poor way.
Lithium should be kept at around 40% charged if you store it for a long time (more than 1 month)
I have 5 batteries with me, 3 of them are considered broken (70 - 60% left)
The last 2 are still in very good condition, around 98 - 99%
About your device, you will need around a few days of charge cycle with a good battery.

Thanks for your answer. I didn't know batteries for this phone are so problematic.
I just charged it to 100% slowly from my PC, will use it normally and see how much the battery lasts and if it shuts down again. As I went through forums, some people say I need to do battery calibration. If it's still bad, I'll return it.
Thanks again!

Try to get a battery direct from Samsung. Failing that buy a PowerBear or Anker. Do a factory reset and calibrate your battery by fully charging it, then running it down to 0% (if it shuts down, keep turning back on until it won't turn on). Then charge fully back to 100% again - DO NOT USE FAST CHARGE.

I will look for a store somewhere. I don't think I can find those two brands here.
I did a factory reset when I bought it a few days ago, but that was with the old battery. Will do the factory reset after I drain it to 0% later today.
I don't have a 'fast charge' charger, and I have it disabled in settings.
Thank you for your response!

What I said before is for all phone that uses Lithium Battery.
Lithium Battery must be kept in a storage at around 40 - 80% charged & must avoid hot places if you don't use it for a long time.
Draining Lithium Battery to 0% will deteriorate the battery faster so it's a big NO.
Calibration is done on the phone not the battery.
Delete "batterystats.bin" to calibrate the battery gauge.
Calibration is useless if the battery is bad (you received it at 0% it means that the storage condition is bad thus the battery is bad.
Charging from PC is a BIG NO as USB port on PC only provide around 500mAh & usually it's unstable.
The charging rate is too low & it could deteriorate the battery faster too.
And the last....I think factory reset doesn't necessary reset the batterystats.bin, so you have to delete it manually if you are rooted or follow this link if you are not rooted.

Thank you very much! I will reply with updates soon!

I had a similar problems, and I have received my new battery yesterday which has been charged in 51% so I drained it to 1%-0% without unexpected shutting downs, I have charged it again and so far it seems to be ok

Hi, I didn't return the new battery after all, I think it 'calibrated' itself after the first charge. Also it goes from 100% to 1% and shuts down properly now.
I did two tests on full battery:
- barely using it, no wifi, data etc, just a few short calls (probably 30 mins of OST) and it lasted almost 6 days
- stress test, wifi and data on, gps with maps and waze on, maximum brightness and and a very long youtube video playing constantly (screen on) and it lasted about 5 hours and 30 mins
In normal use it lasts me about 2 days, but it slightly worries me that if I keep mobile data on all the time it only lasts until the end of the first day.
Would this be considered a good battery life for the Note4?
Thanks to everyone for replying and helping!!
