[Q] new battery

Hi guys,
Recently my nexus battery life became awful. It was never good but it became really bad, like 15%/hour with low usage (some texting and short calls) but wifi+data on (however when i'm turning off wifi it barely change). If i'm using whatapp (for example) without turning off the screen, i can loose 1% every 1-2 minutes. I'm using completely stock 4.1.1 (i9020a if it matter).
I also made factory reset 2 weeks ago, didn't change anything.
I have this phone for a year now but the sticker on the back says that it was produces in march 2011 so the battery is 1.5 years old, probably around it's EOL.
I searched for new batteries, but most of the original batteries i found are 1440 mAh. Mine is 1500. Is this making a big difference? the battery life now is making the phone barely usable but i obviously won't buy a new battery if it won't make it any better...
Any advice about this issue?
Thanks!

1440mah won't change much compared to 1500mah. If you have a custom rom make sure to wipe everything from recovery, re-install your ROM and see how that goes. A lot of times bad battery can be explained by the user usage rather than by defective hardware.
Nevertheless, it's not impossible the battery is dying, so it's not a bad idea to buy a battery. Make sure you buy quality instead of china products, OEM will give you the best results.

Thx, as i said i'm completely stock and recently made a factory reset which is equal to wipe. the battery should be made by samsung, so it's not a china product (or is it? )

No that's perfectly fine. As I said, you don't want crappy unknown brand battery. If it's too cheap too, it could be a copy.
Factory reset isn't equal to wipe though.

OK, thank you! I'll but a new battery and hope that this is the problem

Extended Life Battery tempts me:) (a.k.a. extended battery discussion thread)

So I was surfing the intraweb last night and came across http://www.mugen-power-batteries.co...galaxy-s-relay-4g-t699-with-battery-door.html. Very tempting, especially considering that according to Mugen it has NFC. What do y'all think? Should I?

uuh... the relay is already quite thick, with that battery it will be huge... i personally wouldn't, but it's a matter of personal taste

I had an extended battery on my Doubleshot before this - the bulk didn't really bother me. Maybe I'm strange but I didn't mind. Especially with the battery life I got.

i has extended batteries for my G1 one back then. i used them when i took the device with me geocaching. I had two of them and they made the device stay up longer than i ever did
downside with the bulky back covers is, that the device won't fit into any pouches no more. and, of course cases no longer fit either.
but once you're used to the shape - imho - the added thickness is no longer disturbing.

You can go for this solution....1/5th of Mugen's price:
http://www.hyperionea.com/product/hyperion-samsung-galaxy-s-relay-sgh-t699-2-x-battery-charger/

I had purchased a EZO high capacity battery with cover from Amazon--the same day I ordered the phone. That was months ago and I see the battery is no longer available on the site.
That's a shame, because the package was reasonably priced, the cover fits well, and the battery works as promised.
The device can run about ten consecutive hours for me running CM9 without any CPU profiles and with the governour set to interactive.
If I'm going to be away from a charger for a long time, I've found that setting the device to powersave is tolerable for most applications and the battery goes from good to ridiculous...
The additional bulk will turn off some buyers; however, I have found that it makes sliding the keyboard open much easier...
If you can find an EZO battery and you don't mind the extra bulk, I recommend one.

Nope. No NFC.

I've had my Relay 4G about a month and a half now, and am already looking at getting an extended battery. I find myself charging it a few times a day - sometimes I'll only get maybe 3 hours before it's "critically low". Yes, I do use it a ton - it's currently my main computer, since I rarely have access to my parents' laptop and my desktop, whose case+mobo+cpu I recently sent to the recycle bin, bit the dust over a year ago. Also I have unlimited unthrottled 4G on T-Mobile (and used well over 10-12GB last month, & this (billing) month am currently at 12.21GB since April 28.
I've seen the Mugen 4600mAh battery with NFC online around $90 (way too rich for my blood), and the EZOPower 4100mAh (no NFC) for around $17-23 or so at Amazon or NewEgg, among other places. I was originally wary of the cheap price on the EZO, but if the huge price difference is due to NFC and not being a cheaply made battery, I'd want the EZO, possibly 2. I don't use the NFC hardly at all, and I suppose if I really need it sometime I could pop the original stock battery back in for the occasion.
So any reason for me to NOT get the EZOPower 4100mAh? If I get 2, I'll probably also want an external charging solution so I can charge one while using the other. Also is there a hardshell case (with a built-in stand) available that fits the phone with the larger battery door? BTW unavailability of those two things won't be dealbreakers for me getting the battery. I had an extended battery for my G1, and that phone finally bit the dust after ~4+ years. (I wonder if my SGH-T699 will last that long…)

would somebody care to explain to be why nfc is dependand on the battery?
the batteries have just the same 4 connectors as any other cell battery i always had in my hands.
or are they made of materials that don't shield the nfc waves passing though?

nfc antenna is in the battery casing. NFC antennas go for about $5 on ebay, if you figured out which two connectors go to the nfc you could probably set up your own if your battery doesn't support it.

Can anyone confirm whether the Relay accurately reports on the extended batteries? I'm currently using a patched Droid 3, but I'm starting to find its limitations too restrictive, and I'm thinking of plonking down for a Relay.

I also picked up two EZO batteries. They have a well made cover and last for twice what stock does. Unfortunately it didn't have a NFC antenna and both have now swollen up to the point they no longer fit. While I had left them plugged in after full charge, they seem to stay warm and not tolerate it well. Can't say how well they could have lasted if better cared for, but abuse or overcharging seems to effect them quickly.
Does the mugen or other brands also have issues? If anyone else have suggestions.

Well, it just displays a percentage. It at least seems accurate while logging with Juice Defender's graph, it would track down at fairly consistent rate until charged or out of power. As for swapping over to a Relay, It's about as well supported as any slider out right now. I haven't been disappointed.

ezo
the EZObattery rocks. For $19 (I got mine on ebay) I get 2 days and a few hours into the 3rd before needing a charge.
I have the same issue kilr00y mentioned about it not fitting into pouches or cases except I found now that the phone is harder to flip open and safely hold at the same time while doing 90 other things at once which is when I always need to use the phone. I keep an aftermarket case on the front screen part but can't find an extended back case. I made my own from a tube of black silicone but would love to hear it if anyone finds another option. I don't mind if the phone turns into 1988 brick style size so long as the battery lasts and I don't crack the screen again.

I was looking at extended batteries and if I'm not mistaken, there seems to be a genuine extended battery that should work with this phone. Just would need an extended battery cover. Battery model is: EB-L1K6ULZ (Link)

It looks good. Be aware that most "extended" battery will not last long... In particular when they have a lower voltage than the original battery. Lot of battery with higher mAh run at 3.7V instead of 3.8V this make it last shorter than the original.

I've had 2 of the EZOPower 4100mAh batteries, and am experiencing the same problem that stonefoz mentioned about the batteries swelling. In my case, for example, the current one has gotten to where the cover will just spontaneously pop off, and the battery will dislodge, forcing the phone to lose power. Also, regarding his "staying warm" comment - sometimes when I was doing something extensive on the phone, it'd sometimes get so hot, especially the keyboard area, that I could barely hold it, and that concerns me some.
I believe the second one has lasted longer than my first, though. It's not quite as bad now as my first was when I replaced it. I bought my first one May 18, 2013, and my second one September 18, 2013, 4 months later. It's lasted till now, May 7, 2014, 7 and a half months later, but it's about time to replace it.
It looks like it's no longer available, but I was thinking I should try a different one anyway.
One option is this 4600 mAh Mugen battery for about $90, and another is this 5000 mAh MPJ battery for about $35. The MPJ does say it's only 3.7 volts, which according to scaltro could be a concern with longevity per charge.
I definitely would like better battery life. I've noticed that playing FarmVille 2: Country Escape is quite a drain - I'd go from full battery to getting the low battery warning after only something like 2 to 3 hours or so, even with the EZO battery. Earlier, I popped in the factory Samsung battery, topped off its charge, then decided to test battery life playing FV2. I also turned on bluetooth (and sent the sounds to an external speaker), cranked the screen brightness all the way up, and turned off power saver mode, in an attempt to get a "worst-case scenario". I tried turning on WiFi (we have a hotspot here now) but it wouldn't connect to the game server, so I just went through my unlimited+unthrottled 4G.
The results:
2:45am - battery full, unplugged
4:15am - battery 22% (I checked it a few times along the way periodically, but neglected to note the times)
4:23am - battery 14%, had just gotten the battery low popup warning
4:33am - battery 5%, battery critically low popup warning
4:35am - battery 3%, then I went and plugged it in.
So, it lasted only about an hour and 50 minutes from full to 3% remaining. I'm hoping a good battery would be able to go all day and all night and into the next day with similarly-intensive use. (No I wouldn't be playing games the entire time of course!)
Personally, if the $35 MPJ battery would be good enough, and significantly better than the EZO, I'd prefer to go for that one.
I'm wondering, though, if the $90 Mugen is a huge leap up in quality, though (disregarding the NFC for now which I haven't had to use)? It's a bit rich for my blood to drop all at once on a battery for a phone ... BUT, their website tells me they accept returns up to a year later (and I've gone through TWO EZOs in that time), which gives me some hope. If, overall, I'd be spending less by getting one Mugen and it outlasting 4 or 5 EZOs (if they were still available), I'd get that.
On a side note, it'll be a while before I can afford to replace my phone, but when I do, I'd really like a good QWERTY keyboard. I see that very few phones come with them now, though, and the ones that are are near the bottom of the barrel spec-wise. I'm thinking I'll need to get an external compact bluetooth or USB keyboard with my next phone, and expand my options for the phone itself. Ideally I'd like to get one that I can put in a flip case, with the phone in the other side of it, and close it when I'm not using it. (Although, there is the concern with getting the phone out quickly to answer calls, although I maybe only talk 25-50 minutes a month or so.) Any suggestions on what to look for in the case/keyboard department, for example? Chances are it won't be till 2015 at the earliest (and my wallet hopes my Galaxy S Relay 4G will last through 2016 or so unless it dies or something else goes seriously wrong) before I get a new phone, but I like to start my search early. When I do get one, I'm hoping it'll last at least 4-5 years, and maybe stretch it to 7-10 if I'm pressed for cash then.

My high capacity EZO battery eventually bloated and swelled up--after a year. I replaced it with a Mugen battery. Both came with new back covers and make the device about as chunky as a Sidekick II.
My device can run OpenGL applications for about 9 hours straight with the brightness set to 50%. It's about the same for movies. I get decent signal at my house and GPS is disabled when I am not using it. I use Green Power and Greenify to save battery when the device is locked, but that wouldn't affect using the device.
I am on an official Cyanogen nightly, so there's really no battery saving hocus pocus at work here.
Make no mistake, an extended battery will get you about 9 hours of heavy use. I thought I was going to die when I used a stock battery for a week waiting for my new Mugen to replace the old EZO. The device literally couldn't survive one day of use for me.

Ahh, so your EZO bloated too, just took a little longer than mine did.
Sounds like the Mugen (if that's the one you describe getting 9 hours of heavy use) has relatively decent life. Would you say it's significantly better per charge in that respect than the EZO was when it was good?
Also how is the Mugen for longevity, as in not swelling, etc? If I buy a Mugen, would I over the long term pay the same or less than if I had kept buying EZOs? Paying $90 in one blow seems a bit heavy on the wallet, but I'd do it if I'm getting that much better quality & longevity.

Honestly, I got about the same results with my EZO battery: just over 9 hours of constant heavy use. Other than the fact it swelled up, it worked great. I guess there was a reason it was so cheap...
I had a Mugen battery for my Sidekick 4G before I bought the Relay and it still works great. (I loaned the SK4G to a friend that broke his phone.) My new Mugen hasn't had any problems, but I've only had it a few months.
Combined with TeamApex's Cyanogen and this awesome QWERTY keyboard, my extended batteries have made this phone the most productive and useful device I have ever owned. I can't say enough great things about ApexTmo, the Relay, and extended batteries.

[Q] Tips for Non-Removable Battery

Hello all, thanks in advance for any suggestions
I have a Galaxy S5 that I will be taking back to the store since we haven't been able to get root on it yet, fairly satisfied with the phone.
I had an S3 and then a HTC Thunderbolt before that, both with removable batteries.
Removable batteries have been a huge pro for me, I am often very hard on battery using bluetooth and playing media for 12 hours at a time away from charger.
Really other than being a little tall the battery is what is keeping me away from the M8.
What options does a guy have to combat a non replaceable battery? I know the little pocket power cells have come a long way, and I currently always carry a spare battery now so maybe that is a lateral change. Are there some of those that charge very fast?
I tend to keep phones running a LONG time and pass them down to wife/kids and removable battery has always been a big pro to that.

an external battery like you mentioned or a battery case. if you're worried about wearing out the battery, im sure you can replace it manually after 2-3 years by opening up the phone (there's teardowns posted already). I can't speak on either battery option though bc i have a charger at my desk.

The M8 got a very poor repair-ability score from ifixit so a battery swap won't be a simple choice. Thus my being a bit cautious.

Probably no options are needed. I used to carry a spare battery (or two!) for my T-Bolt but found I could live with the S3 and S4 batteries by keeping a spare battery on a charger and swapping batteries around 6 PM each day.
I was VERY nervous about going to the M8 with the non-removable battery but it lasts and lasts and lasts....... I take it off the charger at 7 AM when I get up and have more than 50% when I go to bed, usually around midnight.
I have a car charger, never needed to use it, I have a USB cord plugged into my PC so I can charge while I'm typing this, never do though, it's not needed.
I can't speak to battery life 3 years down the road when cell phone batteries start losing life but in 3 years I suspect this phone will be as obsolete as a rotary dial phone is now and I'll be looking for the latest gee-whiz phone that is cosmic ray powered or ????
Don't worry about the battery, it'll be fine.
FWIW, rooted, TWRP recovery, running BoneStock ROM (thanks, AndyBones!) with power saver turned OFF!

Thanks for the input! Glad to hear very good and optimistic reviews of the power, thanks for sharing what you are running rooted wise and the like, I am missing being able to do that already on the S5.

YW, hope it helps. You know what works for one may not work for another, right?
When Samsung and VZW locked down the S4 (and later the S3) I knew I wouldn't be buying another Samsung phone, us flashaholics GOTTA FLASH!

I was in the same boat as you. I almost went with an S5 because of the non-removable battery. Not being able to remove the battery is a stupid, and lazy, design idea. I watched a few videos about the battery and went for it. I have to say its at least 50% better than my TBolt. At the end of the day my TBolt usually was at about 30-45%. Now with the same exact usage patterns the M8 ends at 98%. Yeah I seem to only use 2% over an 8 hour work day. I use it on breaks of course. I plan on buying one of those portable batteries for emergency charging and I've got at least 3 chargers in various places. I used my phone at a family event for about an hour and a half. I watched 3-4 youtube videos ranging from 10-20 minutes each at max quality and did some web browsing and that brought it to 75%. Tethering with the WiFi Router app can suck it down pretty fast though. All in all Im happy with how well the battery holds up. Im sure someone will sell a better battery you can replace down the road with a little disassembly.

Concerns about a non-removable battery are overblown now days. If you're going to carry around extra batteries, you can just as easily carry around an auxiliary battery. The smaller ones are the size of a lipstick and are rated around 3000 mah, enough to double the capacity of nearly any device currently on the market. If that's not enough for you they go all the way up to 12000 before they start getting too large to carry around. By the time the battery actually needs replacing, you will likely have moved on to another phone.

how do you expect a 90% metal phone to have a removable battery? i don't see this as possible. you're gonna get tabs that break off very easily or something else that fails bc you want to take your battery out easily.

Extended Battery Photon Q

Hey guys,
I was looking into extended batteries for the Photon Q and noticed that the Droid 4 uses the same battery as our phone. Is it possible to use one of their aftermarket batteries?
I want a slim battery (not interested in making the phone bigger) and this one shows the best results from the D4 forums
Our original battery has some green tag on it as seen here:
http://i.ebayimg.com/00/s/MTIwMFgxNjAw/z/ECQAAMXQUmFSjm2l/$_35.JPG
Is that just for NFC or something else? I don't mind losing NFC if that means I get more battery life

I got the mugen power battery to fit by removing some plastic and the back of the case, and of course NFC. Problem is it would get hot and slow down too often. Maybe that phone, maybe the battery, not sure, never tried it in another xt897.

I went ahead and ordered this gold slim battery
I'll be happy if it's even 10-15% better than a fresh stock battery
I will report back with my findings. In my current usage with one of the latest nightlies, I barely get 1-1.5 hours of screen on time when on mobile data and about 2 hours of screen on time when on wifi

While I've had decent luck with the gold batteries, they are actually just a factory Motorola battery with a shiny gold wrapper put on them. With that said though, at least from the ones I got they seem in every way to be genuine Motorola batteries, so still a good deal. I ended up getting a Mugen too and am working on making a case. I've got one molded up with some bondo but think I might end up trying to make one with super glue and baking soda like another poster did to make it more durable. I can still fit it in the vehicle dock by filing the USB port holder on the dock down a little bit.
If anyone uses the Mugen and happens to use Tasker, I wrote a tasker script to attempt to get an accurate battery percentage from the voltage readings and then update the OS if anyone wants. I also wrote one to keep the keyboard backlight more like the factory ROM instead of following the display backlight like it does in CM.

Just an update. Installed the battery today. I did partially peel off the gold sticker and it was all silver underneath. I know in other threads, the gold battery was reported to be a fake battery, or even stock battery with a new wrapper.
Initial results are good, but it's too early to tell. I will report back with updated usage. So far I'm not even sure battery stats are being reported correctly but it's a drastic increase in battery life.

So the gold battery has mixed results. The first few days I used it, the battery seemed pretty good. About 1.5 times longer than my shot original battery. However I noticed this battery does weird things in reporting numbers. Many times it will report 20% and then drop drastically fast to 0%.
Overall it's a decent battery but certainly not the capacity on the label. I would think a fresh stock battery would perform similarly without the weird drop off.
The biggest difference between my the gold and old stock battery is that it tends to sip power better. When the phone is not in use, the battery won't drain as fast. However when in use the battery drains just as fast. Maybe a little slower with gold, but not a huge difference.
My only concern is sourcing good batteries for this phone now. Even if I found a new stock battery, the unit itself has to be at least 3 years old. I'm sure motorola doesn't make new batteries for this phone anymore...
Wish we could frakenstein a battery for this phone

I would even pay someone if they can make me a custom extended battery like that. Anyone that can help?

I could do that. With that LG battery or a different one that fits better? I don't love that it is thicker by up to 1mm.
I also saw some other eb41 batteries on the market (read my thread here for the 4 I've found ( http://forum.xda-developers.com/droid-4/accessories/best-battery-t3341507). Not sure how good they are, only had the same mixed experience with the gold.

Lenmar still makes batteries for this phone (EB41, fits Droid 4 and Photon Q). I ordered 3 about 6 months ago and there was a 2 month lead time, so they obviously were newly manufactured batteries. I keep a spare in the fridge, the ones in my Droid 4 and Photon Q perform like new as expected.
Note: it won't come with the NFC antenna, but with great care this can be removed from the old battery and reattached.
I would like an extended battery too, but only if it came with a nicely fitting cover. Mugen makes one for the Droid 4 which could be used with the Photon Q, but they don't make a corresponding cover for the Photon Q.
Hope this helps.
P.S. which ROM do you guys use on this phone? I'm running CM 12.1 and it is fine, but when I have a few apps running like Google Music and Navigation, the phone gets super slow due to lack of memory. Under 'Apps -> Running' it shows 450 MB used just for System! I guess 1 GB phones are just passe at this point--or is there a better way to get more life out of this phone?
Cheers,
Mario

Is my phone done for?

My Nexus 5 is more than 3 years old, and I think its planned obsolescence is kicking in.
Its battery life right now is about 3 hours, less with intensive use. I've tried buying a new battery, and even tried it with a fresh stock rom, no apps installed, with similar results. It makes sense to it draining so much battery regardless of the conditions? (I won't post GSam screenshots, since the same happens in these different scenarios).
I mean, I LOVE my phone, I can't think of a worthy replacement for good old Nexus 5... but I can't go on with 3 hours of battery life. Has this happened to any of you? What should I do?

I'm sorry to hear this! I just went through HELL and back to get my nexus 5 back working.. (replaced LCD/Digitizer, USB flex cable, Battery, installed chroot and adb/fastboot on chromebook to flash TWRP and root)
It's an AWESOME device. I would suggest getting a decent battery replacement and look at battery management apps or maybe a battery case? If my phone could be used on Verizon, I'd swap out my Galaxy S6 for the Nexus 5 in a heartbeat..
Best of luck!

I've in fact searched for battery cases, and good battery replacements, but being it a discontinued device is kinda hard (almost impossible). I've bought a battery claiming to be "official", still very bad results. For the case, the only battery case I've found available is this one, and it's a bad chinese battery: https://es.aliexpress.com/store/pro...r-Case-Free-Shipping/1267012_32683454756.html
Besides, I'm from Spain, so any usa store probably won't send to my country.
Any recommendations with this are appreciated!

Some of us have bought a battery replacement in RepuestosFuentes. Here's the direct link. They run out of stock from time to time.
As I said, mine is from there and it's working fine. Also, it has a recent manufacture date printed on it.

I still love my Nexus 5. Recently I paid around $13 to get the battery replaced at LG Service Center here in Bangalore, India and now the phone is back and running. Installed AOSP 7.1.1 and it's running as smooth as 6.0.

Actually, I'm not so sure a new battery would make things a lot better. Thing is, any battery attached to my phone just drains extremely fast (maybe some hardware issue?), so... replacing a new internal battery can make things better, but not much, since it's a internal battery.
The ideal solution would be a good battery case, so I can add that to its normal battery. But, as I said, I didn't find one that seems trustworthy for sale right now.
