Improving battery life

Hi all,
I would like to make my battery life for my phone better. I would like the opinion about external batteries and after market batteries. I just don't know what to buy. Should I buy both?

I've heard stories that Juice Defender in the market is worth it, may want to check out the free version.
I also recommend the stock battery for the EVO Design 4G, fits perfect in our G2/Desire Z and gives a little kick over stock. If you are looking for a monster extended battery that requires a new battery door, check out the battery thread in Accessories.

A lot of folks on here swear by so called "higher capacity" 3rd party batteries like Seidio and others.
But a while back, a guy on here did a bunch of testing of various 3rd party and OEM batteries on various phones. He found that the expensive, so called "high capacity" or extended 3rd party batteries almost never met their rated mAh. And often even tested lower than the stock (lower rated) OEM battery.
He wrote up his test methodology and results very comprehensively. It looked to be done pretty scientifically, and I take more stock in this than anecdotal evidence. Can't find it right now, but its a great writeup.

If your looking for a bigger battery I can vouch for the extended ones @ htcpedia, Having purchased a few myself.

That aside your can try flashing a different kernel, for better battery life.

I have the Mugan 1800mah, after flashing a new radio (the newest one from T Mobile) and the matching RiL files my battery is lasting longer. So far on a single charge and moderate use I am getting around 36 hours.

I brought this CHICITECH set (2x1900mah batteries and a wall charger) http://www.ebay.co.uk/itm/220648053...X:IT&_trksid=p3984.m1427.l2649#ht_5383wt_1185 and they arrived about 7 working days after in the UK.
I only got them yesterday, but already i have noticed a big difference. I had a stock battery before but these are lasting between 30 and 50% longer. I have heard good reviews about them before and they seem good so far.
You do need to remove the sticker and cut off a small bit of plastic to make them fit reasonably, but for the price your getting what appear to be 2 good batteries. Mugen slim batteries are a ripoff IMO.

So EVO 4G batteries would fit with some modifying? Hmm i think an external battery would be better for my use than carrying spares.

Get 2 batteries and keep one charged in your wallet, works a treat and doesnt add bulk

Just out of curiosity how long does ur average battery last? I can usually squeeze ~14 hours with moderate use. if u don't want the bulky feel I would suggest just getting another oem battery as a spare

Idea:
Grab one of those Energizer charge-on-the-go things with a micro-usb plug and use that to rapid charge your phone when you need a boost mid-day.

^ Just an idea.. I would substitute the lithium batteries with rechargables so that you can charge those up overnight and have them ready for the day too.
I have the stock battery and it can last about 19hrs on moderate use (10hrs on heavy) on Virtuous Quattro overclocked to 1.2GHz. Never had my phone die on me even when I ran Sense ROMs (after a 3 day break in period =p)

I'd get both a aftermarket and a OEM, Run a test on both to see which works better for you.
I recommend Mugen's 1800 mah
http://www.mugen-power-batteries.co...nded-battery-for-htc-desirez-t-mobile-g2.html
And HTC's EVO Design 4G 1520 mah
http://shop2.sprint.com/NASApp/onli...oryID=BSH1373&topPageNumber=0&subPageNumber=0

I don't know if you've tried juice defender app before but I think it helps. Not a lot but you can tell that it improves a little. I think the app kills the date, wifi, when it's in sleep mode and turns back on when you wake and use your phone.

Extra battery comparison

So I have the TMobile S4, the regular battery, Anker's 2600 mAh batteries, and unbranded 3000 mAh batteries from ebay.
What's the go-to battery tracking app? I'd love to know how these things really are, because just as I expected, the 3000 unbranded batteries don't seem to be lasting as long as either of the 2600's.

As a general rule of thumb, it won't ever last as long. You can't put more battery into the same space ( generally speaking ) or it would come that way from the factory. To get a bigger charge battery, you get a bigger ( physical ) battery along with the new phone back.

I feel the anker battery is a bit stronger than the stock, and the ebay batteries go way too quick, so I really wanted to test them. I figured the ebay battery would be a little thicker and I'd leave the back cover off, but the case on, but it still fits under the cover.

I thing, from Galaxy S3 battery are usually with NFC able, but i will ask question from that about this. Even , I need strong battery, because i make couple days testing. My opinion: LTE (4G) network is worster from 3G for original 2600 mAh battery life, and for my way using, on 4G my original battery about hallf of thay live. Not enought for me, because i order this 5200 mAh (2 pieces, because i have speciall universal Sohsine charger for all handys). Wenn coming after test will request opinion about.

high capacity batteries

Hello guys, I wonder if you can help me at all. I have a Samsung gt-i9000 running android 4.3 at the moment . When I upgraded the OS (I was on 4.0) I have noticed that the battery life decreased dramatically, It lasts no longer than half a day. I have already changed one battery but with not much success, so
I started to look into high capacity ones. I had a look around and found a few reviews here and there but not specifically for the gt-i9000 – even this useful one here http://forum.xda-developers.com/showthread.php?t=1956293 . So I wonder:
1)has anybody tried one of these high capacity batteries on the gt-i9000? I looked at the zerolemon 7500mAh and the anker 52000mAh - although I don't know whether these are compatible with my phone;
2)I presume that the high capacity batteries are actually thicker than the default 1500mAh I have at the moment, so when you buy one do they come with another back cover?

Hi, I recently bought a Polarcell 1800mAh battery on Ebay which gives me half a day more juice on Galaxy running CM 10.2. I found out that all batteries above this capacity are massively thicker than the original one and do require a wider back cover. Most of these bigger ones are shipped together with a back cover.
Regarding your questions about the zerolemon, I only found batteries for the S2 and the S3 which wont fit for the S1.

not your battery at fault, sounds like you got wakelock issues. with your rom.

thanks guys.
 @zegovernator I think I need something more powerful than 1800mAh so I might need to get a bulky one. I have found this http://www.ebay.co.uk/itm/3000mAh-B...-Extended-with-Black-back-cover-/150981110923 that seems to be good enough.
 @slybunda, thanks for your comment. If it is an issue with that, would you know how to fix it without me buying another battery?
thanks

use app called better battery stats and see the individual wakelocks I had issues with google currents and hangouts both which I don't use so I disabled them and got my full battery life back. have a look for one of my posts in the i9000 battery threads got screenshots of very good battery life

Got 1800 battery from Anker, very good.
Only charges slowly with the car adapter.
Depends on kernel and rom for how long it lasts.. Was very good using android 4.3 but recently battery was discharging fast after gapps update.
Fine again now on kitkat

Buy from Ebay 1800 in good price,I did =)

GS4 Extended Battery Recommendations Please

Hi all,
Looking at maybe getting an extended battery for my S4, but I want to keep it as slim as possible, while also being worthwhile having though, no point something with a useless battery gain
I really like the design of this one where the phone sort of 'slots' in for two reasons:
1. I think you can use the original battery as well as the extended?
2. I like the way it doesn't look like it will add too much thickness
http://www.amazon.co.uk/GooseWhite-...4&keywords=samsung+galaxy+s4+extended+battery
Only thing is that has useless reviews
Does anyone have one they would recommend?
Thanks!

I had one similar to that. I don't think it's worth it. It gets hot when it charges and it doesn't feel like I'm getting full extended battery cause charging and using your phone cuts the battery imo. I'd just get a regular extended battery. I have this case it's expensive but I like the size and it does add extra battery. It's uNu Unity Samsung Galaxy S4 Battery Case [Black/Silver] - External ... http://www.amazon.com/dp/B00GBHRHHK/ref=cm_sw_r_udp_awd_GvRjtb1C8GNQN
Other than that I was using the hyperion 7200 mah battery for awhile. But the unu is my favorite at the moment because of the size

Hmm that unu does look quite good, if I'm correct it only adds ~1cm to the phone?
Looks very very nice actually! I think I'm going to leave it though, had a think and I'm always near a computer to charge my phone, or in the car, seems like £40 that can be spent/saved elsewhere
Thanks though

Sorry but that is way too chunky looking for my liking. The Unu looks much more 'original' I'd say

I have just bought the uNu Unity battery case for my Samsung Galaxy S4 (August 2014) and I am very impressed with it. Coming from an Exogear Exolife Battery case (which I already like - bought it last year around November), the uNu Unity Battery Case is a significant improvement. I got back my full functionality of the USB port, which is compromised when you use a traditional battery case that piggybacks your phone on an external battery via the microUSB port (the battery case USB port is usually not data-capable - charge only). I also noticed a significant increase in battery life. With the Exolife Battery case, I use my Galaxy S4 for around 10 hours on a typical day before switching on the Battery case to charge the phone (around 15-20% charge remaining). The phone gets hot while charging and I only get it charged up to around 60-70% capacity before the battery case runs out of juice. Obviously having the phone on while charging from an external battery pack is not the most efficient mode of charging, so I get an additional 6-8 hours of moderate use out of the phone with the Exolife battery case.
With the uNu Unity battery case, I was able to use my phone for 19 hours (more than adequate to a typical day) with the battery life at 60% after that time. The last time I was able to use a smartphone with this kind of battery life was my old Palm Treo 650 which lasted 3 days on a charge for me...
Overall, I am very impressed with this battery case. The uNu Unity battery case works like an extended battery without the ugly backplate that typically comes with extended batteries. And you get to keep your NFC functionality since the NFC antenna of the Galaxy S4 is part of the battery. Also, unlike the Exolife battery case, the NFC signal is not blocked by the external battery part of the case so it remains functional.
There is some creakiness to the case when you handle it, but when I removed and re-installed the battery case, I managed to fiddle with it so that all its clips engaged properly, making the gap between the backplate and the new bezel flush, thus minimizing, if not eliminating the creakiness of the case.
And compared with the Exolife Battery case, the Unu Unity battery case is shorter and thinner as well.

New battery for the S4

Hello guys,
I am only getting 2h SoT on my S4, the phone gets really hoooot and the battery got "bigger", so it's dying. Which one is probably the best one to get? Anker, Zerolemon, Ravpower or anything else? I used some Anker ones on my previous phone and was quite happy with them.
How much SoT/battery life could I expect on a battery like these?
Cheers!

Some people said that ZeroLemon fixed the stuffy audio problem on their batteries now it has a space above the speaker, so you'll not have problems with/about this.
Never bought an Anker battery, i cant say too much about it, there are another threads about this battery in this section. But comparing ZL and Anker both have similar results.
I dont Know RavPower.
I have an ZeroLemon myself, everyday i got 9-12h screen, even after 1 year.

I bought one of these.

I got a RAV Power battery for my S4 off of Amazon for 12 EUR and I've been using it for a week, on stock vanilla firmware (but this is another story).
I get out in the morning at 8.30am and I use my S4 in the car for navigation (Waze) and music (TuneIn Radio or Google Play Music) for 1h a day (30 mins in the morning and 30 mins in the evening), then some calls, emails, whatsapp, etc. (no games or exotic stuff) and I usually get back home with a 40% battery around 7pm.
A colleague at work bought a Duracell after market battery for 24.50 EUR and he's not satisfied as the new battery gets very hot during simple use and he have to charge it at least one time during the day.
It has been just a week, but I'm pretty satisfied with this RAV Power battery!

Zerolemon 7500mah user here nothing to complain about.
Music sounds good because it has a gap between the battery and the speaker it actually made the sound better or somewhat amplified because it has space inside the TPU case that comes with it.
Using this 7500mah for close to 2 years now and still gives me 10-12hrs SOT max per day.
I use iPhone charger 1A and charge it only when i sleep, upon waking up its full charge.

after inheriting a S4 im not very happy with battery life, its a replacement off the bay..ie fake..so which one should i go for,,im in the uk so i dont think all the battery makes are available to me easily..cheers

ZeroLemon and Anker seem to be popular replacements.

thanks, yep defo need a new one, 38% before bed time and 2% this morning, think ill go with anker over ravpower

im actually in two minds wheather the battery is knackered, i put it in safe mode last night and it drained 6%, maybe a app is causing it, gsam battery stats doesnt tell me anything is draining it, maybe im over thinking it and just need a new battery full stop, the last one was a cheapo off the bay
one thing i did notice is when i charge it to 100% gsam is telling me its at 1200mah, weird

If you're in Canada and want a cheap fix, the Source is clearing out some $0.96 CAD battery cases for the S4 (and S3). Lots of trade-offs with using a battery case, but it's the cheapest solution.

I bought a "NFC-compatible" Perfine battery and the NFC didn't work.

I'm a big fan of MPJ batteries - the standard size are maybe 10% better than stock, and I personally rock a 8,500mah battery all the time. Used on the S4, Note 3, Note 1, and others.

zerolemon
hello friend, I am looking to buy the battery zerolemon. you can direct me to a secure site to purchase?
