Hello all. I posted about a week ago in the Verizon s5 section with regards to bad battery life while living in Germany. I have gotten exactly 0 feedback over there, so I figured I would post my question here.
Admins - I am just copying and pasting. Unless you think it would be better to just move the post?
Anyway -
=============================================================================
Hello all. This is my first actual help post cause I now have a problem, but I have been lurking for a while.
Anyway, I have a rooted S5 from verizon that had awesome battery life compared to my old nexus - I could hit 2 days with one charge. Anyway, I am now living in Germany, will be here for the next year, and I can get maybe half a day before I hit 30%. It feels like I am back with the nexus, I have to plan my charging around what I will be doing.
My carrier here is Lebara. Under the battery stats Android system and Androud OS dominate usage. I had that under control in the States with some TB tweaking, but it is back with a vengance. I haven't updated the OS and am not planning to until L comes out and is compatible with root.
I am never far from an outlet, but I don't want to return to my old habits of always plugging in.
I just had a thought - is it possible that the different electricity standards here nuked my battery? If this is the case, should I worry about my tablet too?
I am also starting to notice a lot more lag and even freezing from normal usage.
=============================================================================
Tl;dr?
Moved to Germany with rooted Verizon S5. Now using Lebara. Half day battery life. Starting to notice lots of lag and freezing. Help!
I noticed that there have now been reports of the S7 and S7 edge exploding in the same way the note 7 has even giving a guy 3rd degree burns. This got me thinking about the two s7 edges I've had and the quality control issues that may be plaguing our devices as well. My first s7 edge had great battery life, 6 hrs+ SOT, and ran cool all day. I then returned it because a better promo came out within 14 days of my purchase and got a new one. The new one has never made it past 3.5 hrs of SOT and runs hot all the time. This is with the exact same apps installed, the same settings, and initially the same firmware. I've tried running 100% stock, FDR's, freezing apps, rooting, and tweaking just about everything with little to no success which makes me wonder if this is a hardware related issue with the battery. Maybe this explains how some people are getting 8 hrs of SOT while others cant make it past 3. It's a definite possibility in my mind that we have the same or similar manufacturing defect in the s7 edge as the note 7.

I've never gotten anywhere near that much screen on time. Mine's more in the 3 hours range maximum. If the screen is off, my battery seems to decently, but I've never seen the crazy high numbers that many others have.
My SOT is rather high, but I only experienced battery issues after rooting the first time with the 935V kernel. After moving to 935U, I went back to VERY cool CPU & Batteries, and better SOT.
Hot S7
Try turning off all of the Amazon crap if you don't use it. They tend to use up a lot of battery time when they are running in the back ground, and by default they are installed and set to run always. That might help a little bit.

Google any device and you'll find cases of a few burning. That's just the state of LiPo technology at the moment.
The Note 7 has had upwards of 30 cases in a very short period of time, and a known quality issue from a particular manufacturing partner. What you'll find with the S7/S7E is nothing near that severe, and on par with contemporary devices like the iPhone 6/6s.
Update: I called Samsung and I'm not even kidding here's how the first part of the conversation went:
Me: Hi I have a galaxy s7 edge and I'm a little concerned because it is draining quickly and the phone runs very warm and sometimes hot.
Agent: That is not good! Are you hurt?
Me: No I'm okay
Agent: Thank god! Please power the phone down and send it to us. We will fix it or send you a replacement within 5-7 days. What is your imei number and email address?
I got an email within 5 min with a return authorization and then called verizon because I don't want to be without a phone for 5 days. I told them the story and they are sending me a replacement and I just have to send the old phone in. Either Samsung is being super cautious or they know there might be an issue with our phones as well. Either way I'm looking forward to seeing if the replacement is any better. I saw that a couple of people have reported getting referb phones that run cooler/better.

i believe theyre over 90 now lol.. i doubt theres a defect in the S7/S7E, ppl are just wary now after the N7 recall even though unless you do anything crazy theresasmaller chance of it atually exploding..
i actually take my phone off the charger for a few mins if i feel it burning up lol
My phone has been doing this. Getting super hot and the battery goes from 100% to 0 in 2-3 hours. I'm gonna call them

If I remember correctly they had a factory issue and had to outsource like 10% of the note7 batteries to a different company. They didn't do that with the s7e to my knowledge so if there is an issue it's probably not related to the note7 issue.
I had this issue earlier this week.....phone wouldn't even last a normal 9 hour shift at work and I was down to under 15% by my lunch break. Lost my mind going back to stock and reflashed stang Rom 3 times...the third time I forgot to install greenify and the problem was solved. Reinstalled greenify and my battery drained like it was a countdown clock. Went back stock, reflashed and didn't bother with greenify, just rolling with forcedoze and have 0 issues. Currently at 32% and I've been off the charger for close to 12hours and even had to use my flahsight for a solid 10minutes
My original Samsung Galaxy S7 Edge ended up literally melting all USB cables and chargers that I plugged into it. This was roughly after 4 months of owning the device, it always got really hot while charging, but one day it started smelling like burning plastic. I successfully got a warranty replacement on that device, my current S7 Edge still gets hot after charging, but nowhere near the original device.
I would venture to assume that 'fast-charging' is the culprit behind overheating, as you are pushing 2 Amps to the battery (compared to your usual 700mAh - 1 Amp standard USB charger).
As the Doctor stated -- you will always have SOME defects in a very small percentage of devices. As the S7 Edge has been out longer, I would say we are okay
Samsung Galaxy S7 Edge got the Oreo update lately and the battery was just draining like crazy. On top of that, charging it seemed to take up to 10 hours and draining it less than 1.
Never had an issue until update. Fresh installed using Odin (direct 8.0 AP). Still draining like a wild fire burns.
Are there ANY solutions to fix this? I'm not sure what more info to provide so ask away and I shall answer you. I know it's a short question.
So to cut a long story short I already have an S10 plus from Samsung however the battery life was shocking so I sent the device back for a replacement they're being really slow with the replacements so I'm tempted to just request a full refund. I have been looking at the snapdragon S10 plus and how much better it is on both battery and performance and wondering if it's possible for it to work in the UK you can buy it for about 850 quid from certain sites. wanted to know if anyone has any experience with using an American or Chinese snapdragon in the UK and if you still get updates and full connectivity?

I had the same issues with my phone before, I requested a replacement and now I have not had any issues I tweak the device to my likings and not issues presented. Also one bug that was draining a lot of battery was the VoiP calling bug (whatsapp or facebook call) will activate the proximity sensor and it will prevent the phone to go into deep sleep, only way to solve it was restarting the device, now there is a software update that solves that issue called ASCA.
Also I don't know how you restore your phone, I avoid any backups from smartswitch or google backups, I set up my phone from scratch to prevent any corrupted app settings. This has been my battery usage, before posting I changed the display to FHD+ before it was in WQHD+

Your battery life is much better then mine I have a s10 plus which I bought through Vodafone on contract I unlocked it and installed the March update the BTU version through sammobile this was my battery life even reset the phone and installed everything with no backups I only had 3 hours 42 minutes screen on time standby of 14 hours and 14% left
Hello guys, I'm using rooted S7 edge currently, and about to root my S10+ so I can use the phone (rather than using it and wiping it later).
However since It's been awhile since I root my phone, I came across a few posts claiming that Samsung phone starting from S8 or newer will have limited battery capacity if rooted (like this one for example).
Is this still true? Is this also a problem on S10+ because my S7 Edge is fully charging even with root.
Mine says 4000mAh in Castro, so I don't think so

The 80% battery capacity was due to the root method using a eng bootloader/kernel. Not sure which been a while since I've rooted any devices
