I am not sure...when I tried at batteries+ i couldnt (however that wasnt stock and was a little thicker, rayovac I believe)...I am actually waiting for 2 oem s3 batteries in the mail (should be a little thinner than the rayovacs) my hopes are high but i am prepared to do a little modding if necessary to gain 300mah if the t399 can manage the 2100mah size, the mod would only be to the battery cover and only cosmetic.

EDIT:
[MENTION=2930656]autonomous[/MENTION], thanks for the heads up, looks like Ill have to make some subtle changes to the cover to get it to work (i expected that actually)

[MENTION=4401198]Baddude8[/MENTION], Walmart had a big deal going for a week (last week ended 8/2) @49.98 for these (univision owned by tmobile) and they were selling like hotcakes, i picked up 2

Honnestly i think it wouldnt be a bad idea to heat it up and then try and form the back cover around the larger battery

You can really get better battery life by disabling cores... Ive used this on a galaxy light and it does what it says https://play.google.com/store/apps/details?id=com.mugich.cpumulticorecontrol&hl=en
[Samsung Galaxy Light Guides, News, & Discussion] vjgrace:
forming the cover (not a bad idea)...did u notice if using the s3 battery showed improvements? or did u not use it long enough to tell?

thanks for the link to the cpu app :)
[Samsung Galaxy Light Guides, News, & Discussion] autonomousperson:
Yeah it had amazing battery life :D
[Samsung Galaxy Light Guides, News, & Discussion] vjgrace:
wow, i am really excited now...I have 2 batteries on the way and with a small modification to the cover I may use the s3 battery permanently.

thanks again.

From the kernel sources and other places, I think this phone uses the Exynos 3470.

If anyone wants to overclock, try editing drivers/cpufreq/exynos3470-cpufreq.c
[Samsung Galaxy Light Guides, News, & Discussion] autonomousperson:
Allright I'll take a look at it when i get home
[Samsung Galaxy Light Guides, News, & Discussion] jin03002:
The cpufreq for exynos is a bit different from others so it might be weird for you to edit.

I think the kernel that I compiled will let me overclock but I'm not sure yet (I'll test it probably over the weekend).

If you need any help, feel free to ask

Hey, I'm trying to port ParanoidAndroid 4.6 to the Light. I've got nothing but time on my hands and dammit I'm going to get this done. I'm sick of Touchwiz. Anyone able to help if I need it? I already got the device tree and such from jin03002 on Github, all of AOSPALegacy's stuff, now to start.

Also, from what I've gathered, this device is exceedingly similar to the i9305, right? So I should have the proprietary files from that?

Thanks, just sent him a message. I wonder if he's got a booting rom yet? That would speed my effort up greatly presumably. Honestly, I'd even rock CM on this thing, ANYTHING but Touchwiz. haha
[Samsung Galaxy Light Guides, News, & Discussion] mn1968:
Sorry to bring up an old topic but did you ever find a separate wall charger just for the battery? I am in a situation where the phone will boot/turn on but turns off immediately because the battery is DEAD and won't charge in the phone. I purchased a new battery but the problem appears to be with the phone charging. Been going nuts trying to find something to charge the batteries. I'm about 95% sure that if I can charge the batteries the phone will function perfectly fine (aside from not charging the #@%$#^ batteries!)

I noticed people talking about using S3 batteries in their Lights...wondering if this would work for charging the T399 batteries.

Thanks,
[Samsung Galaxy Light Guides, News, & Discussion] tazmaniondvl:
I found out the one I have does charge the battery just fine :D I have had it so long, the only thing I know about it, is it came from amazon woth 2 batteries for my old phone (galaxy exhibit 4g SGH-T399)
[Samsung Galaxy Light Guides, News, & Discussion] mn1968:
Thanks. Just to confirm, the Light is T399. Is your old Exhibit the T759 or T679?

Also, does your external wall charger for the Exhibit (T759) look like this? Looks the same as this one listed for T679.

Hmmmm.
[Samsung Galaxy Light Guides, News, & Discussion] Planterz:
PA wouldn't be my first choice, since it doesn't have the icon or nav button customizability as some other ROMs like CM, Liquidsmooth, Slimkat, or Mahdi (among others). I've been trying different ROMs on my Nexus 4, and immediately dismissed PA because I couldn't change my nav buttons around. Of course, this wouldn't matter with the Galaxy Light, and I know I can used Xposed to tinker with status bar stuff, so if you want to try PA, then I'm willing to be a guinea pig. Anything AOSP or AOSP based. Anything other than TouchLagWiz.

I'm still playing around with different ROMs on my Nexus 4 until I can settle on one (and then kernels), after which time, when I can be satisfied with it as a "daily driver", I'll be happy test ROMs for my Galaxy Light. I won't be of any help with coding, but I can test drive and report bugs. The only reason I haven't tried Lightwave yet is because until I'm done tinkering with my Nexus, my GL is my back-up device, and I don't have a back-up for my back-up.
[Samsung Galaxy Light Guides, News, & Discussion] mn1968:
Seems I may be totally hosed.

A while back I posted that I had dropped my Light in the water. It dried out fine and did initially boot up (when plugged in), and I could use the phone (while plugged in) but the battery wouldn’t charge. At that point I bought a new battery to no avail. While attempting to charge the new battery, the phone popped up a message that charging was paused because the battery temperature was too low. This now happens every time with both batteries. It boots up then shuts down immediately due to a critically low battery.

I was convinced that if I could charge the battery externally then I could just pop it in and use the phone. Unfortunately, that is not the case. A coworker charged the new battery with his external S3 charger (lights went from red to blue, indicating a charged battery). When I placed the “charged” battery in the phone, it booted, said the battery was critically low, and shut down. Plugging in the phone doesn’t help – it boots up, displays a message about low battery temp, then shut down. So, exactly as it was before.

Any advice? I know I shouldn’t waste any more time on it but I’ve become obsessed with this little project. Heck, I was even able to boot to download mode and follow Shabby’s guide to restore completely to stock. SO that has me thinking there is still hope for this POS.

yes i did i gave it to my son and he cracked the screen so we had to get a new one and got the samsung galaxy light t399 witch is very much like it so easy to root and install cwm but damn there is no roms for it well there is one but its the same rom with out some tmobile addons

This is a much better phone, just waiting on CM11 then we will get a ton of roms, im good at porting, Just not building.

If you can find the thermorersitor i guess you could try to see if it is somehow damaged.. or try to remove it completely. There are some kernel tweaks to prevent phone from shutting off if power is too low and there are also tweaks to ignore battery temperature. you could ask someone to back up their rom with those tweaks and you could try to restore it onto your phone
[Samsung Galaxy Light Guides, News, & Discussion] mn1968:
Thanks for the tips about the kernel. I have found some kernel apps that sound like they may (or may not) accomplish what you mentioned. When I have time this weekend I'll re-root the phone and try some of them out. If it works - great! If not, well, I already ordered an external battery charger similar to what you linked. I'll see if that works or not. Worst case, I take it somewhere and if it can be fixed relatively cheaply, then I will go that route. It's a shame because it is (was) a good phone...I really liked it, Wish I hadn't ruined it.
[Samsung Galaxy Light Guides, News, & Discussion] autonomousperson:
The Wanam moduel for exposed does alot of what I mentioned. Can you get into recovery without it dieing?

How do we request galaxy light forum? There are plenty of other phones with almost zero development mainly due to locked boot loader that have their own forum. Here we have root, recovery, and a stock ROM. More than many on here
[Samsung Galaxy Light Guides, News, & Discussion] darkgiant:
I bump this too! I actually picked up this phone for my brother, and it is really a nice little phone with all the features packed onto it!

I of course cannot contribute much in terms of development for this phone, but I'd love to see a growth of Samsung Galaxy Light users on XDA!
[Samsung Galaxy Light Guides, News, & Discussion] vjgrace:
I agree 100%.

This little phone is amazing:

--no locked bootloader

--no samsung knox junk (in bootloader) as the new flagships have

--amazing battery life (i use samsung galaxy s3's 2100mah battery permanently and can get up to 9-10 hours DISPLAY ON time, of course dependent on data or wifi usage)

--quick example, i am typing this out on opera mini, the phone has been on for 2 days 4 hours, i am at 38% battery life and have had DISPLAY ON time at 7 hours (awesome)

--nfc (even though i dont use it)

--LTE

--voice over LTE

--quad core cpu

--dual band wifi (pretty sweet to have this option with dual band routers)

--gps (pretty standard these days on the smartphones)

--flawless miracast mirroring

--1gb ram (completely adequate, unless a big gamer...even the new iphone 6 and 6 plus have only 1 gb ram)

--this little guy really does the job and can be used comfortably with one-handed operation, which is difficult with the new flagships and >5" displays (and with this phone there is even less two handed fatigue with prolonged usage)

...and the list continues, even with the lower resolution you can tweak the dpi for better appearance

really happy with this little unit.

I sadly can't recommend it due to all the bugs I experienced using it.
[Samsung Galaxy Light Guides, News, & Discussion] mav361:
Vjgrace did you mod battery cover to fit with the s3 batt?
[Samsung Galaxy Light Guides, News, & Discussion] vjgrace:
yes, i had too.

i tried to form it with heat (of course separate from the phone and battery), then used a small grinder on the inside to gain as much mm as i could, definitely worked but i like what i am using better now, so i tossed out that one.

what i have now isnt the prettiest but extremely functional and maintains the form factor amazingly, with the s3 battery only adding a couple grams to the weight and with 300mah more battery power...i used razor blade (box cutter) and cut opening where the new battery sits within the cover, while keeping as much plastic as possible, then applied adhesive black vinyl cover (used some extra i have laying around that i used for a tablet skin...it is flexible in nature) and on the underside (where contacting the battery) simply applied some saran wrap on the adhesive to keep it from sticking to the battery and then heated it with hair dryer to assist adhesive contact and to improve formation.

this was all done while the battery cover was separate and i used extreme caution while cutting the plastic, virtually repetitive scoring until precise cut was made.

the result is something great, just not too pretty (but heck how often is the backside seen anyway).

battery life example from time i wrote earlier post today:

writing this in opera mini (26% life remaining) 2days 12hours 30minutes phone on and with 8hours 15minutes DISPLAY ON/SCREEN ON time.

best smartphone battery life i have ever encountered and i have had the galaxy s3, s4, s4 minis, motorolas, and multiple xperia smartphones.

hope that helps :)
[Samsung Galaxy Light Guides, News, & Discussion] louforgiveno:
Do ya have some photos of the mod?
[Samsung Galaxy Light Guides, News, & Discussion] vjgrace:
sure...zipped 'em up (pics too big to just post, sorry), feel free to check them out.

as you can see the mod maintains the original form factor perfectly, just a few extra grams in weight overall but for 300mah more power, it suits my needs perfectly.

now be warned :) the battery cover doesn't look great from the backside, but it is the backside and as long as the user isn't saying look at my mod, no one will ever know, lol.

take care.
[Samsung Galaxy Light Guides, News, & Discussion] mav361:
Sweet nice mod I have the xtra batt thinking about the mod as well but I am pretty good on batt life with stock batt iam rooted stock rom debloated xposed wanam, gel settings I love this phone
[Samsung Galaxy Light Guides, News, & Discussion] vjgrace:
ya, even the stock battery is amazing, you really dont need to do the mod because the stock battery life is so good with debloated stock rom, i believe i was able to get 8 hours display on time with the original battery.

one thing to mention if you use the s3 battery is you will need to mod the battery plastic tabs that hold it in place very slightly (to avoid unnecessary pressure on the galaxy light's frame). also i use an external charger because i rotate batteries so i always have a fully charged battery when the battery is low...i actually have never charged the s3 battery in the light. it would probably charge fine, i just have never done it yet (have not needed to with my setup) :)

finally make sure the s3 battery is oem or else it is very possible you wont see a difference in battery life with those fakes out there.

just a few things to think about if you use an s3 battery.
[Samsung Galaxy Light Guides, News, & Discussion] vjgrace:
hey all,

Both the T-Mobile and MetroPCS versions just got an update a few days ago. Does anybody know what changed?
[Samsung Galaxy Light Guides, News, & Discussion] Planterz:
Has nobody gotten the push update or tried it? If I download the update on my phone it boots into TWRP and doesn't update. Rebooting after that causes persistent system UI crashes. Good thing I did a back-up first. But after restoring, the update icon won't go away, and I have to keep postponing the update.

I'm downloading the full firmware, but it'll take several hours (assuming it doesn't screw up and I have to start over). If I flash this, is it considered a "dirty" flash, or will it replace everything and I'll have to start things over by scratch again? I'm adept at flashing on my Nexus 4, but I'm unfamiliar with doing this with stock Samsung firmware.
