I've got an S4 and need to upgrade. The one major issue I have with the S4 is the poor battery life. I'm about to order a new S5 but can't decide between the standard S5 (with dual-SIM adapter) and the S5 Duos. I'm a landlord and need a second SIM on the go for my tenants to be able to reach me during the day. I can achieve dual-SIM capabilities with a standard S5 by adding a dual-SIM adapter from ebay but this doesn't give the same functionality as the Duos, not necessarily a bad thing though. To resolve my decision I've got a couple of q's if someone would be good enough to help:
Does having two SIM's on standby all the time have a big impact on the battery life of the S5 Duos in comparison to the standard S5? I.e. does the standard S5 battery last longer with just the single SIM?
I need to be able to turn off one of the SIM's at night to stop tenants calling out of hours. Can the second SIM be turned off via the UI or does it need to be physically removed? With dual-SIM adapter and using the UI I can easily switch between (and therefore turn off) one of the SIM's.
Thanks.....:good:
1. No, I don't think so. As there is just single antenna in the cell phone anyway. Battery impact is from my point of view not noticeable.
2. Yes, sim card manager allows you to easily enable/disable sim cards as you wish on the fly.

Thanks, I'm guessing you have the Duos?
How do you find battery life in general? How long do you get out of the Duos?
I'll get less than a day from S4 with only minimal use. I'm looking for better from the S5 Duos.
I have duos, and I get day and a half on average usage.

please can anyone link a dual sim adapter tested on s5 that allow dual standby? thanks

I've noticed something, hope someone can confim this; I've used my 7.7 tab with a SIM card inserted but removed it last week as I'm waiting to get a new SIM in the mail from a different provider. It seems that when there's no SIM in it the tab uses more power, the battery is drained quickly.
I'm using a custom ROM on it (Tweaked Stock for GT-P6800 Version 2.0)
Anyone out there who can confirm this?
cheers

I can confirm this, all samsung tabs seem to use more power when there is no sim card in them. You can try to enable airplane mode, this should turn radio off, but you can still enable wifi.

yes i can confirm my tab is consuming more power its like 10-15% an hour only wifi is working browsing internet
so i should consider putting a sim card to prevent hig drain of battery
turning airplane mode doesn't help
if someone can confirm it ?
I can confirm that even turning airplane mode when a simcard is present is causing higher power drain which is totally weird.

There's a mobile network setting and use packet data enable/disable it concerns also battery
Did anybody try switching radio off via the "test menu"? (dial *#*#info#*#*)
Sorry if this is a silly question. Just gathering info before deciding what version to get. I'm presuming that the WiFi ones don't have a sim slot at all, so this affects just the 3g ones? Did think that is was odd that I have heard a lot of people say that battery life is very good and some like yourselves say the hourly consumption is high.

This is pretty lame. I wonder if I used a non active sim, how it would behave. I don't want to buy a plan right now.

Hello,
I bought my phone a couple of weeks ago. At first, I didn't notice it, but after a few days I began to realize that the phone discharges completely after less than a day. I looked up and found the battery thread where I saw people going on about how happy they are with battery life, but others complaining about it draining real fast.
I found out all about wakelocks, and fast dormancy etc, and tweaked everything to the max, but the drain was still going on like crazy.
I thought maybe the stock ROM is bad and I need to use something different, and was about to flash, but then as a last resort I decided to try another sim card - I have 2 cards on the same line, one of which I use for my ipad - and swapped it.
Ever since, all the problems are gone! I even enabled fast dormancy again and I see that I have ~1% per hour drain when the phone sits still...
So, to anyone having large drains from cell standby with no simple and obvious explanation, I suggest trying to swap your sim card!
Hope this helps someone...
How can the sim card cause battery drain?
I'm still using the simcard from my last phone, though I still have the new simcard that came with the s3 but its not activated yet.
A guess is that the simcard caused connectivity issues and as such threw the phone out of fast dormancy all the time.

Lucky you, my provider decided to disable the old sim card when they handed me the S3. By consequence I could not, as promised, call my gf who got mad at me ^^

we cannot have 2 different sim cards of the same no. in our area.
btw, does your sim card have different specifications? which one is newer?

The second one is newer, but was meant to be a data sim and had "Laptop" written on it, though it accepted and made calls just fine, but did not get sms until I asked it to be configured as the primary. Both of them were cut out from regular sim cards, because the providers here decide it is funny to charge around 25$ for giving you the same product with less 1 gram of plastic on it...
Today I got a normal micro sim (I guess they thought I already had one, and replacement is free) and it is also working completely fine.
I think the contacts in the old sim were causing high resistance because they were really worn out, and thus some extra power was lost on them.
I'm pretty sure most companies offer an extra sim to put into a car phone. Here it costs around an extra 1.50$ a month. In any case, my point wasn't about switching between 2 sim cards, but rather that a new sim card might cause less drain. You can believe it or not, but it worked for me. I can post before and after screenshots even.
So has anyone tried changing Sims for better battery life with success?
Same with me. I was having 2-3 % drop per hours, not sometimes the battery remains at 100% after 2 hours of inactivity
Ever since i bought my G3 i was experiencing heating issue. Despite the v10j update, my phone was heating up. The battery life was also so so.
Everytime i ran antutu, my phone used to reboot. I gave my phone to LG service center and they finally helped me pin point the fault in my device. The sim card that i was using was some 4-5 year old and i had coverted it to a micro sim by cutting out the edges using a stapler like cutter.
This was what caused all the issues in my phone, Now when i have bought a new smart sim, that is pre cut and comes in with an adapter, i face no heating issues whatsoever. Besides, my battery life has increased significantly. Switching to ART gave another boost to performance. I am connected to wifi all day, my battery lasts 30+hrs and i get 4.5 to 5 hour SOT.
In a nutshell,
Dont use self-cut SIM cards, rather go for a factory made micro SIM.
Switch to ART, Its the new king.
Very strange that it would act like this. I wonder what about a cut sim card that would make the phone do this.

Exactly, being an electronic & communication engineer, my mind also got boggled on hearing this, but the service center guys have daily life experiences, so they could figure out the fault. Besides maybe, my SIM might have been faulty over years of usage.
Hello,
mabye it's a good idea to post you battery life with Single and Dual sim options.
Beceause me and some others notice a "drain" on converted Single Sim devices
On android 6.0 Single Sim rom i've got like 4 days of stand-by time
On android 6.0 Dual Sim rom i've got only 2 (Installed 3 days ago)
Is it really the second sim that is consuming this amount of battery??
In my battery overview "Mobile Stand-by" is the highest
And i like to know if you are facing the same problem, or do i need to settle the battery through some recharges?
Hi,
I'm currently looking for a new phone. I find the Galaxy S7 and the Galaxy S7 Edge very interesting en beautiful devices, but I have one question where I cannot find an answer for through Google. With my current phone (Galaxy S3), after a few months the charging was going very slow. I know it is a common problem for a lot of phones. The solutions provided by internet: get a high quality adapter/cable, turn the device off while charging, use a battery saver app etc. etc.) are not reliable and/or expensive solutions. I see a little improvement if I use another cable/adapter but the only good permanent fix I had for this issue is using the boeffla kernel with a parandroid ROM. In this kernel I can configure a fixed charge current en I can ignore unstable power (so the phone doesn't negotiate with the poweradapter about how much current it takes, the phone takes just the current I set). I know it could probably damage the poweradapter/phone battery, but I'm willing tot take this risk when I can charge my device always quick, no matther where I charge my phone and with what cable/adapter.
Back to the S7 (Edge). If I google for "slow charging S7" I see lots of people that have problems with charging, simaler as I discribed above about my Galaxy S3. I know the Galaxy S7 (Edge) has quickcharge 2.0 support, but that only works with quickcharge enabled poweradapters. And for example, if I need to charge the phone in my car or with my powerbank (that doesn't support quickcharge), and probably even after a few months with the standard cable/poweradapter that comes with the device, I'm afraid charging wil go very slow again.
So my question is: Is there an solution to set also a fixed charging current for the Galaxy S7 / Galaxy S7 Edge? I'm planning to root my phone and I'm probably going to install a custom ROM, so I don't mind installing a custom ROM/kernel as long as it's stable.
Regards,

I have had my s7 edge since it was released here in the uk and I can tell you that it charges at the same speed and time as it did the first day I got it. I have not experienced any slow down . The only thing I have experienced is that the battery is lasting longer after each update the s7 edge recieves. It takes about 1 hour and 30 mins for my s7 edge to charge up from 5 percent.
Ok, thanks for your message! Well, I guess I'm going to buy the phone and hope that charging the device quickly won't be a problem.
