Hello everyone,
A while ago (right at the launch of the S2, total coincidence) I made the transition from a "regular" cell phone to a so-called smartphone.
I took a look at the S2 and liked what I saw, but read absolutely horrible things about the battery (i.e. not being able to get through a day with it). To me, that's not an option as that means I can't rely on it and thereby defeats the purpose of a mobile phone for me.
So I looked elsewhere and got me a Motorla Defy (installed Cyanogenmod 7.1 on it). I'm happy with this phone as the battery usage is okay to me; during the week it easily lasts a whole day to 36 hours with plenty of room to spare (not going to claim a consistent 48 hours, but it could get there every now and then). It gets these easy 36 hours with the following usage pattern:
- Internet connection is always on (it switches automaticly between wifi and mobile internet depening on availability)
- a few widgets (stock quotes) are always on and refresh about once every 5 minutes
- e-mails refresh about every 5 or 10 minutes, not sure, I'd have to check
- usually facebook app is on as well in the background so I get notices when somebody sends me a message
- regular texting during the day
- a few calls every now and then, usually only a few minutes a day
- reading the news online with the browser, not constantly but checking every now and then
- general browser usage while looking for adresses or random info etc
- little to no gaming
A few days ago somebody told me that the battery problems with the S2 had lessened due to new Android updates and such. As my brother needs a new phone I was thinking on giving him mine and getting an S2 myself, if battery quality is any good.
So basicly, my questions:
1) can I expect the same battery durability of the S2 as from my Defy now that the problems are supposed to be fixed
2) can I also put Cyanogenmod on it (as I'm used to this and like it) without any battery problems
Any information or feedback in this regard is much appreciated, thank you.

Moving to Q&A
No thoughts on this?
Battery use is very hard to gauge because the phone doesn't do exactly the same every day. In essence, estimates on battery life are like MPG ratings for cars: different styles and circumstances dictate usage.
Having said that, the less the screen is on, the greater the battery life, in general. If you are not happy with battery life, there is an official 2Ah battery which should yield around 20-30% extra usage.
I don't think SGS2 had any real big battery problems, or at least my set has never had big issues. Pretty much the same battery capacity since I first got mine and now with the newer firmware versions.
At the end of the end it all depends on how heavy you use your phone, how strong WIFI/3G/2G signals you obtain, running apps/widgets etc. Sure, the battery life is not great on SGS2 but it's also no worse than other mobiles with similar screen sizes.
I'm sure you can manage 24h with your usage, if not then you can always later buy the higher capacity battery which Samsung have released. It's slightly thicker but barely noticeable.
i got my s2 about a month ago with 2.3.3, battery was pretty poor at the start, wouldn't last a full day, but with some tweaking, i can now get roughly 2 and a half days use, albeit with light use. currently looking at my juice defender status in notifications, and says phone has been unplugged for 57 hours.
what i did/use.
2.3.5 stock firmware
juice defender ultimate
froze wifi sharing, ap mobile, social hub with Titanium Backup
screen brightness down to about 20%
turn off wifi when not needed
Basicly, what I'm wondering about is whether, given the use above, I could unplug my phone at 6am on friday to go to work, and only have to plug it in again at 8am on saturday with room to spare for any unforseen circumstances
Seems I finally found the question to which no answer can be found on the internet
Hello, new guy here. Thanks for having me here.
Did a search for the issue, but none thread found comes close. I did an update on Monday (24.03.2014) OTA to 4.3. Of course it failed - forgot to do factory reset before that so what I got was famous samsung screen with blue LED on. Long story short, managed to recover. I had all the usual after-update-battery-drainage issues, but after tweaking and forcing shut a lot of stuff it is much better. Except for screen.
When I use phone with screen on, the battery level drops almost visibly. I would estimate it at 1% for 1.30 mins. What's more - when I use Google Maps Navigation in my car, the phone loses charge even when plugged to the charger (old trustworthy TomTom USB, rated at 1000ma). Slow - about 1 percent for 7-8 minutes, but still. Oh, and phone gets very hot then. With screen off (power button or automatic off after 30 sec) the battery life is awesome and it charges like a sponge. even with constant H/H+ internet connection, audiobook player with headphones on and of course phone services. Comparing to "before update" its much better. Of course it may be due to lot less freeware (read: adware), but it is better.
However, screen is a killer in this deal.
60 hrs uptime, 15h 15min on battery, 47% of it screen usage. Next is Device Idle with 13%. During that time screen was up about 5h total, of that 3h while plugged to charge. I also went through two audiobooks totaling 20 hrs, browsed net (heavy with the downloads - 3gb total) for 2h, used Kingsoft Office for 2h and navigated with google maps for about 4h, did about 3.5h calls, emails check every 10 min (just headers), some texts and camera. All times approximated, but fairly accurate.
Phone is 1,5 years old, is and always was stock. Bought in UK, used in UK, locked with H3G (Three).
Does anyone have some advice? Tips? Tricks? suggestions? Much appreciated.
Thanks,
Adam
What you have is normal, you need a new charger is all and probably a new battery. 5hrs screen on time from a full battery is the best you can expect..

Thanks for quick reply.
Well, since my SGS3 is 16 months old I would say that max screen for me would be bit less than 4h. Battery was used and abused (had message about it being too hot for charging a few times etc.), but right now it is more like 2h on scree time. And NOT charging while navigating is new. Started right after update. And this not charging issue is of supreme importance. I've a roving job over quite large area so I'm driving a lot. And sat nav is a must. And since it's draining battery even on charge it worries me as phone is used extensively - technical chats, calls, online and offline documentation etc.
Anyway, will change the charger. Battery... Have half a year till end of contract, so will think if I need the expense.
Oh, one more thing. On Monday my SanDisk 32gb SD died - that's why I updated. Wasn't sure which gave. I had unexpected unmount message with this card. Could this issue use more battery as well? different card now.
Thanks again.
Sd card issues will drain battery. Charging stops when the battery reaches 50°C so if you are navigating and don't point an air vent at the phone it will overheat and stop charging.
Batteries last six months before capacity is reduced, after 16 months you will be lucky to have 50% the original capacity, less if it has ever overheated.

Oh, that I know. I'm hard on batteries, but not in phones. None of my phones ever had failed battery pack, but laptops... all of them. But that's not the issue.
Battery is essentially low energy chemical reaction, so obviously it will be degrading. No issue there. That's why I'm not shooting for max parameters and not worried about it, especially since update phone lasts more. Waaay more.
I changed chargers and it's the same (I have two more never used TomToms and one Tortoise rated at 2 Amps). So i'm starting to think that the issue is not batter, charger etc. I think Google Maps on navigation (which uses simultaneously Screen, GPS and internet) also goes on max on CPU and GPU. that's why tere is overheating and not enough power for everything.
So it looks like software issue. Google maps in particular. Do another factory reset? Everything is up to date. Or maybe I overlooked something?
Partial solution found
Hi all,
Sorry for late update, but was out of the country and all that.
Thanks for suggestions. They were useful to solving most of the issues.
First, changed cables, not chargers. cleaned also contacts in the socket of the phone, so battery gets charged well and fast all the time. And is even better after couple of cycles of full discharge/full charge.
Probably because of having less "apps for free" it is simply phenomenal - normal sync (incl. emails), normal gsm, heavy music listening - takes about 5-7% of battery charge per hour, depending on signal strength. It is much worse when working with screen on, but still good - about 5-6 hrs of gaming for example.
There is still issue of excessive battery drain while using google maps, but this may be software issue. will be uninstalling/reinstalling it soon. Should help.
Will inform on that one as soon as status changes.
Hello,
I have a Smartwatch Android Snopow W1S.
This Smartwath has Android 4.4 Kitkat.
The problem is that the Smartwatch always shows 100% of Battery when the Battery is charged at maximum and it does not descend for 1 day o for hours depending of use, but at any moment the charged descend very quickly and in 5-10 minutes the watch is power off and without battery.
I tryed with anothers apps of Battery indicators and all of them showing the same 100%.
Also, I tryed a Battery Calibration with apps from Play Store but the problem continue.
I think that it is a bug specifically of the Android ROM of my device, because I had another similar Smartwatch Snopow and worked perfectly.
The Smartwatch is new and under warranty,but the shop where I bought the Smartwatch already reinstalled the ROM and it had this problem.
Are there any solution for this problem?
Anybody has had this problem?
Thank you very much,
I wait a response.
The issue is the knock off smart watch. Other then trashing it and getting a new one there is nothing you can really do.
Just received my stratos last night and everything still stock. Went to sleep at 92% at around 1am and now 12 hours later it is at 61% with no music, gps usage. Only notifications and barely any interaction. Rebooted both phone and watch just in case that worked, but no.
Kindly advise why this 5 day battery watch is gulping away my juice?
So i read that bt is likely the culprit. Mine also constantly disconnects and reconnects even when watch and phone are with me.
I just changed setting to keep amazfit app always running and not to optimise bt tool, bt and amazfit app. Think this will prevent disconnect/reconnect? Let's see if this will stop the draining.
Or am i fighting a futile battle against a bug?
1. A few phones, notably Huawei models, have a problem where WiFi interferes with Bluetooth and you cannot get a stable connection, you can test this by putting phone in Airplane mode and enabling only BT and mobile data.
2. The watch may have bad antenna, to test this, pair it with a BT speaker or headphones and see how far you can get from the watch with the speaker/headphone. If it disconnects after only 30-50cm them probably it has bad antenna (normally GPS doesn't work as well in this case) and you should ask for a replacement.

It actually got disconnected after about 120cm away. Do i have a bad antenna?

120cm isn't very bad, can be interference. Bluetooth and WiFi use 2.4GHz frequencies. Any improvements when away from both your phone and router?
Non that I could notice.
Right now, the watch is in airplane mode and it barely lost 2% over the last 3hrs. I noticed when it was draining battery earlier on, bluetooth on my phone depleted 84% and almost killed my phone.

On average my is loosing 6% per night with continuous heart rate on and one alarm in the morning. I am on latest international firmware. Make shure that you do have a watch face which is updating only once a minute. Auto back light should be disabled at night.
My watchface has weather, calories and steps. I woke up with 93% at 6.30am. Auto-airplane mode off at 7.30am. It is now 79% after 7 hours just using notifications. Not very impressed with battery life. At this rate, I have to charge it daily or it will go flat in less than 3 days. I don't even dare to turn on continuous HR.

You are probably receiving a lot of notifications. I don't need notifications on my watch. It is for sports and I have a smartphone. Comparing to Garmin Vivoactive 3 I can say that battery life for me is the same. One exception is during long duration cycling it is consuming more energy because of the bigger display which is always on.
So far maybe about 30-40 Whatsapp messages/notifications. Is this a lot?

I lost 10% within an hour that was when I noticed it was disconnected and failed to reconnect back. At this rate, it isn't even going to last me 2 days. This is really disappointing.
Try doing a factory reset on the watch. This fixed battery issue for me. Before it ate the battery in 24hours with nothing enabled. Now its 1 day 12hours since last charge and 81% remaining.
Worth a try..
Why would a factory reset be necessary on a new watch? It is less than 48 hours out of the box with nothing installed. Would a factory reset even be useful in this case?

Anyway I went ahead and factory reset the watch. Hope it clears this battery drain issue.

Beats me. Should'nt be necessary. But it worked for me. Hope it works for you too.
It's gone crazy after a reset. The charging will disconnect/reconnect non stop, even when attached to a PC via usb outlet. Stratos' drive will connect/disconnect non-stop as well. The only way I can charge the watch now is if I switched the watch off, if not it can't charge. It doesn't appear to be a charging issue since it can charge when watch is off. Factory reset multiple times and updated to latest fw still the same.

Until today i havent even gotten 2 days of usage out of the battery. this is depressing.
Battery drain issues
My new Stratos also facing battery drain issues here, at first when i pair my watch to my phone (Samsung Galaxy Note 3) is was fine. Battery drain percentage was not too horrible. On the next day, my watch started to received notification regarding my phone is too far away from my watch, but i notice that my phone is just nearby my side. Plus, this notification can be received a couple times a day. Then i notice that my watch is drain battery very fast, about 10% per hour.
On the same day, i unpair my watch from my phone (Samsung Galaxy Note 3), and pair my watch to another phone (Samsung Galaxy Note 4). *Note, please backup your data from your watch if needed, because once you unpair the watch from phone it will do a factory reset. (Is a pain in the ass that i have to re-download the watch face again). And charge up my watch to full 100% at 10PM at night and leave the watch bluetooth continue pair with my phone over night. On the next morning around 6:30 am, when i check on my watch battery percentage, its only drop 1%.
Still unable to confirm whether the issues is it cause from both of my phone having different BT version (Note 3 is BT 4.0) and (Note 4 is BT 4.1), or my Note 3 is already old and the circuit board are having problem. I still need to monitor this battery drain issues on my Note 4 to confirm the result. Hence, I'm not a heavy user, i don't received a lot of notification everyday.
Hello,
new product came out, and that is Amazfit GTS 2. Anyone already have the watch? Can 1 week battery life still be achieved if all features are turned on?
Thank you for the answers, I really appreciate it.

This guy is a long term supporter of GTS and GTS2. He praised a lot for the old GTS and its amazing battery
But in his review of GTS2, after using for 10 ten days, he said the battery is really PATHETIC, only last like 2 days.

I saw this video but this is the only one that is saying the battery life is 2 days...so I'm looking for more users that can verify this before I buy it...
Thank you anyway
I found two more review on battery test for you.
https://www.igeekphone.com/amazfit-gtr-2-in-depth-review-2/
In terms of battery life, according to the official statement, Huami Amazfit GTS 2 has a battery life of up to 7 days in daily use mode. I turned on the active heart rate detection + sleep assisted detection mode, turned on the sleep breathing quality test, and used the watch according to my own habits. The power consumption was 29% for 28 hours and 12 minutes, and the battery life was about four days. If you follow the official daily use mode instructions, the battery life will be further extended, and 7 days does not seem to be a problem.
https://www.androidcentral.com/amazfit-gts-2-and-gtr-2-review
What's honestly most impressive of all is that the developer's battery estimates for these smartwatches don't appear to be overblown, a rare thing for smartwatches or tech in general. After a week of use, including using the always-on feature sporadically, tracking my sleep cycles, and going for several workouts with GPS activated, the battery only recently dropped below 50%. Keep in mind that it would drain faster if I had continuous heart rate / SPO2 tracking enabled, but for most users, the GTR 2 could easily last you up to two weeks per charge. For comparison, the GTS 2 has a 7-day battery estimate.
Hope it helps, bro.
Personally, i'm using GTS and see no reason for the upgrade to GTS2. If you haven't bought GTS before, then maybe it's worth it.
No me llega las notificaciones del WhatsApp,
Alguien le llega?
Ya ta solucionado.
I have the gts2. I've had it about a week. Battery with usual use is about 4 days. I have wrist flip detection on high and get about 3 days. Overall I really like the watch. Waiting for Alexa update to come in the future.
I have the GTS 2 since the day it launched in India. Love everything about the watch except battery life.
Battery drain is too much. Hardly getting 2 days. I find it absurd to first purchase smartwatch for its features and then keeping most of them off to get battery life.
It is possible to turn WiFi off and bluetooth on?
Hello, I have it and only two days of battery life. I have a week with him and the clock is not bad at all. Taking advantage of the thread, you know how I can activate the extra functions of the watch.
I bought a few days ago GTR 2, and all is almost perfect except for the battery... firstly from 48% to 10% within 24h, . After fully charged, 3 days and 50% has gonewith one, 1h training per day without GPS.
I like multitasking, wifi (fast watch faces synchro), but AOD drains battery a lot I decided to disable AOD, sleep tracking, switched heart rate to 10min. interval and after 24h battery decreased from 56% to 44%, while I know that people with GTR 1 have 1% per day with almost the same settings...
so I'm really disappointed with such battery life...
Do you have any advices?
@Redmundek, my girlfriend has the same problem. I bought GTS2 for her and GTR2 for me and with the same settings I get ±10 days of battery life and she gets ±3! Did you find any solution?
Have you checked the settings for detection method? Try different option and see:
- automatic heart detection - for me it is Ok
- Sleep assistant - may be the root of possible more draining
- Automatic heart detection & sleep assistant - potentialy draining battery a lot (as far as I remember)
Then other options below: activity detection, heart rate alert, all-day stress monitoring, sleep breathing quality.. I have ticked most of them after different tests. No issue with battery draining (I guess)
I'm using a GTR2 but I remember having seen a big change in the battery draining here when I tested different settings.
Good luck.
Hi, I amended sleep monitoring and stress detection and the battery is quite good, even with AOD from 7:00 till 22:00 (which I prefer) it can works c.a. 5-6 days
