S4 loses charges really fast and sometimes goes off even when it says there is 45% left [R]3 years, 8 months agoidreamincode posted submission on galaxys4.
Jan. 15, 2016
My s4 in the past 2 weeks has suddenly started losing it's charge really fast, for example it was on 100% at 2pm it's now 3:40 and it is on 30%, ive been using it but not excessively and only I read emails/ messages.
Also sometimes it will randomly turn off mostly when its around 30% but today it went off when it was on 50%. It will reboot but then go off again before anything is actually loaded up. It comes on again once i put it on charge.
Would a new battery solve this or is it a phone malfunction?

Its a samsung galaxy S4 from ebay
the model number is GT-L720 and the thing is its running low on battery quite often so i was thinking of picking one up, but not sure which type of battery to find.
Are the different kinds for S4?
Sept. 25, 2015
Yes, there's more than a dozen variants of S4.
The L720 is a Sprint specific model.
They should use the same battery though. B600BU

[Discussion] Is The Samsung S4 Obsolete? Worth an upgrade? [R]4 years agoiknotcare posted submission on samsung.
Aug. 18, 2015
So I have a Galaxy S4 that I've had the past 2 years. My only real complaint about it is my battery life sucks (even with a replacement battery).
My contract with verizon ends soon, and I have the option of getting a new phone. Ideally, I'd like to use the S4 as long as possible, I don't need the shiniest and newest gadgets. However, I'm worried that it won't be supported soon and will be obsolete.
What are people's thoughts about the S4 at this point? How's the battery life on the newer S5 and S6? That's what's really killing me with the S4.

If it is just the battery, buy a new one: http://www.amazon.com/Samsung-Galaxy-Replacement-Battery-2600mAh/dp/B00BW0X892
If you want to upgrade, get the S5, not the S6. The S6 had no SD card and no replaceable battery.

[Request] How long would it take to charge my mobile phone using a Tesla super charger? [R]4 years, 3 months agorawrmage posted submission on theydidthemath.

You didn't state what cell phone you have, so I just picked an arbitrary cell phone, the Samsung Galaxy S4. This phone appears to have a 3.8 volt Li-Ion cell with a capacity of 2600 milliampere-hours, which corresponds (3.8 V * 2.6 Ah) to a capacity of 9.88 Watt-hours.
The most powerful Tesla Supercharger can deliver, according to motortrend, though it seems to be hard to find detailed specifications, up to 100 kilowatts via 400 volts DC at up to 250 amperes.
Assuming you could convert the 400 volts DC down to the 3.8 volts DC you'd want to recharge the lithium-ion cell of your phone battery with 100% efficiency, you'd get about 26,316 amperes available to charge your phone at that voltage. (100 kW / 3.8 V = 26315.7 A)
You again are, in the real world, going to encounter more inefficiencies in the circuit which regulates the charging of the battery, but let's just ignore them. At 26.315 kA with a capacity to charge of 2.6 Ah, to find the resultant time it would take, you can simply divide - 2.6 Ah / 26315.7 A = 0.355 seconds.
Phone dying while on the charger [R]4 years, 5 months agoLittleHelperRobot posted submission on galaxys4.

My S4 is almost two years old. I've loved it, but today it has caused me some problems. It started when I was brushing my teeth and my cat knocked my phone into the sink. It wasn't in there but 2 seconds. I dried it all and it seemed to work the same. Well the past few hours it has been dying extremely fast. It is at 13% right now and it's been on the charger for hours. I use my phone for work and to talk to my boyfriend of three years who is hours away. I really can't afford to go without it. What could possibly be wrong?
Edit: I forgot to add that the where the phone and charger connect it is lose and wobbles.

Is there a way to force 3G on a modern device? [R]4 years, 7 months agoRedPill115 posted submission on tmobile.
Feb. 15, 2015
Specifically an S4. I tried messing around with the ServiceMode menu but I got no results.
I also tried getting into ##4636## menu, but it didn't work (Instead of opening the menu, the phone actually tried to call the number).
Anyone got any ideas?
By the way, I'm wanting 3G because Tmobile's isn't that bad at all, and it may save me battery. My S4's battery is already deteriorated after so much use and recharge and uncharge. I can live on EDGE, but I'd be better if I could use 3G instead.
Feb. 16, 2015
I don't think there is a "3g" on TMobile. There's 2g (Edge), then it jumps to 4G (hspa+), then it goes to LTE.
If you want to switch to hspa+, or edge though, here are the steps that I ran across last week while playing around with my phone (they do work from personal experience):
Make a choice, different choices will connect you to different kinds of data including lte, 4g (hspa+), edge, or not data at all.
But - if your goal is better battery life, doing this is just plain silly. You probably won't gain anything, but you can buy a whole new battery for your s4 for $8-$12 on amazon.
$8.29, 4 stars
$11, 4.5 stars
$12, 4.5 stars
One of the advantages of the s4 is exactly that you can remove the rear cover and replace the battery yourself.
[Galaxy S4]Is my battery dying? Or is it even worse... [R]4 years, 10 months agoReallyObvious posted submission on techsupport.

VZW Galaxy S4, rooted, Hyperdrive RLS16.1, bootlocked.
So for the past month I've been noticing issues with my S4. I will pick it up, only to realize that it is off for some reason.
Last week one day I woke up and noticed that it was running in the "high-heat" mode. For some reason it was really warm. And even though I left it on the charger over night it was at around 50% charge, In the time it took me to go to the bathroom and come back to my bed it had lost nearly 5%, and all that i did was check my email and open the facebook app.
Over the past couple weeks I have been noticing that sometimes it uses power faster than it charges.
Each of these issues was resolved by popping the battery. I am only using the stock charger and cord. I have been using Hyperdrive for a little over a year (not unlocked bootloader).
A few minutes ago I picked it up and it was off. I turned it on and it had 1% charge (it had 100% 12 hours ago, and I have barely used it at all today). I am unable to use it. I put it on the charger and it will automatically power on. It will power on to 0% power, then shut down. then it will power up again at 0% and then die again. I have tried popping the battery, but it is not working this time. It is getting very warm around the camera lens while it is trying to charge, I'm also getting that "slow charging" message, even though I'm using the stock charger and cord. I checked the battery and I don't see any bumps or anything, it is completely smooth on all sides.
I have had it since release day, and there is not a single scratch or ding anywhere on it.
I do have the full extended coverage from VZW/Asurion. Can I walk into a VZW store and ask for a replacement battery instead of swapping the phone? I live out in BFE and none of the VZW stores around here have the "tech centers".

Leaving charger plugged in after full charge = detrimental to battery. True or False? [R]6 years, 1 month agoAug. 9, 2013
Let's settle this. Some online literature specific to the S4 claims that when the battery's charge is full, leaving it plugged in to the charger will wear away at future battery life.
I'm not completely sold on this, because a) so many of those articles about "battery saving tips" are filled with dubious ideas just for filler and b) it seems like the phone would have a function telling the charging port to stop completing the circuit to the battery once it reached capacity.
Personally, due to how quickly the S4 charges on the factory charger/battery I never really need to leave it plugged in overnight, usually I can juice it up all the way in the morning before I go to work. On the same token, though, if you inadvertently left it plugged in at full charge for six or seven hours would it really hurt your battery's lifespan?
Coming from a couple of phones that had TERRIBLE battery life compared to the S4 (Nexus S and HTC EVO), I used to leave them plugged in at a full charge all day while I worked so they wouldn't die five hours after I left. I can accept if maybe that made the batteries worse, but I kind of doubt it.
