Possibly going to get an s4 - Galaxy S 4 Q&A, Help & Troubleshooting

Just got rid of my Xperia Z and my iPhone 5. Just have a few questions before getting one. No point asking the people in the shops they just want to sell.
The battery life on my iPhone 5 was pretty good and it charged very quickly. Yet the Xperia z was awful drained so fast at least it charged fairly quickly. But the iPhone charged well on the USB whilst being used where as the Xperia Z only charged if you didn't use it on USB.
Is the battery life on the s4 better than both or similar. Is the USB charging issue an android thing.
Also the Xperia z had a poor wifi signal. How's the s4's
Any other tips would be nice.

Overall the charging... is super fast in S4 because the charger out put was 2A and the battery also heats when charging but not so long ...
My i9500 is very smooth can handle any games you throw at it. The battery is not good currently hope be samsung fix it in future update. I just give my opinion.
You the decider for buying it! DON'T blame me if you not satisfied with it.

I would like to start with Sony Z i used for a week and hate that device coz of battery , heating, sound quality.
And compare to Sony Z ... S4 is far far better starting from battery , perfomance display music some of the software features etc
ii cant tell u diffrntce between S4 and I5 as i never used it
And if u are a high user of the phone u myte need to have a xtra battery or can use a custom kernal like persues which gives u a option of underclocking etc and u will never regret having this phone
Note I have I9500 and as of now it does not supoort CM10 etc and I9505 does support
for the variant u have to take a call
But S4 is worth a buy anytime compare to device u have used for sure

I have the gt9505 variant.
The battery Life is very good when on a custom kernel, I use ktoonsez kernel for instance and it allows me to make a profile to reduce the max ghz used when the screen is off. Greatly improves battery Life Imo. Also allows you to set the GPU max mhz when screen off.
On stock however I didnt really like the battery Life. I came from a note 2 which has fing awesom battery Life.
It's not bad on stock but the iPhone 5 will last longer I think.
Also depends on your usage of the device tho.
Check some battery Benchmarks which are around on the web.
As it stands right now iirc the 9500 loses to the 9505 atm in terms of battery Life.

Switching to S2 from htc

I dont want to flame, but i have some deal to switch my Desire HD for S2.
is it really that worth ? I mean, i am amazed with Hd (custom rom ofc) and battery life (around 2-2.5 days) and i read about S2 having bigger issues with battery (around maybe 1d) :/
HTC Sense is also a big plus for me tho
should i get S2 ?
It sounds like you have already made up your mind. If you have to ask if its good or worth it, you dont want it.

Maybe you are right !
But i just wanted to hear something like "You can tweak your phone, so battery will last longer. use xxx rom..." (same thing what i did with HD)...

As someone on this forum said , the S2 is only a software update away from being the most powerful smartphone around ( not taking the 4.65" screen on Nexus into account ). Adreno205 and 1GHz Snapdragon on Desire HD just can't compare to SGS2. And about the battery, one day is enough really , who uses their phone for 24 straight hours... Jack Bauer maybe -.-

That, you can do, of course.
My dad has a Desire HD and it's slow as ****. I would never consider or recommend anyone getting a DesireHD over a Galaxy S 2.
Hvala !
Are you kidding me? I had a desire HD also it had a 1230 mah battery and lasted 8 hours max for me. My galaxy s II easily lasts 2 days if I want it to (with about 5 hours screen on time). Try CheckRom or Androidmeda if you do get the Galaxy S II. But if you have enough money, you should get the Nexus. Its the best phone out right now

My reply might have been a bit terse so apologies for that bad work day haha!
Its a very, very good phone, hopefully good enough to grab the phone of the year award. If youre up to a bit of tinkering you can make an amazing phone into one so awesome it could slap the baby jesus and walk away unscathed.
Its a definite jump from the DHD but as with all tech, increase the power and screen real-estate without a jump in battery technology and you do get worse battery life. With the frankenstein ki3 rom and speedmod12 kernel I get around a day and a half to two out of it with low to medium use.
Hope this has helped!

Thank you all..ill get it
I bought an s2 two days ago. Moved from a desire HD.
I was getting about 30 hours using rcmic runny rom. I was happy with it but fancied a change.
I have rooted and unlocked the s2. I have tried CM7 and MIUI roms but have come back to a Samsing KK5 rom with a few minor tweaks.
I have siyah 2.3 kernal overclocked to 1.4 ghz.
Battery life is about the same ss the desire HD but i have noticed that the samsung takes twice as long to recharge.
One thing i do need to say. This is a very very fast device.
I loved my desire HD but the s2 is a better device all round.

if you've already bought it then perhaps u can try CheckROM Revo HD 4.0 with the latest speedmod kernel
for me its the best combination if u want better battery performance

Not sure where you're getting your info from but the Desire HD's got worse battery life than the Galaxy S2.
I was one of the DHD early adopters back in late 2010 and yes, as someone else mentioned here, it's slow as **** compared to the SGS2. I don't know why anyone would prefer the DHD over the SGS2. My phone lasts me 2-2.5 days just with a rooted stock 2.3.5/2.3.6 ROM. I only use SetCPU and App Quarantine to freeze apps.
I am so glad to have sold my DHD!!!
i have had the desire hd and its not in the same league on any front. better everything honestly. Dont be worried about the battery. custom rom and kernel and it will easily last you the FULL day on heavy use.
Neboj se, ove je najbolji phone sto mozes kupit
You can get the official 2000mAh extended battery from Samsung like me, and battery life will be even better. With this battery I have not once gotten mad about my phone switching off during the day, somehow my battery life has increased with 50%.
Anyway, Desire HD to Galaxy S II is a good move. First of all, the screen are just as big, but the Desire HD screen looks ugly and washed out compared to the beautiful sAMOLED+ display on the S II.
Second you upgrade from an old Snapdragon processor to Dual core exynos, which is seriously must faster.
I also believe the camera is better on the S II.
I would to it no doubt
Regarding battery! Basically he is comparing his personal use on dhd with reports of power users on sgs2. In short if your dhd lasted you with your usage pattern 2-2.5 days you're sure to be within 3-5 range on sgs2 provided you continue to use it the same way.

Thank you all..
Btw, i am mid user.. 10-15 calls, 1h wifi/day...when i first got DHD, my batt after few weeks lasted less then a day..like 15-16h... Then i rooted and falshed few rooms, stayed on Virtuos. Now i have 2-2.5 days mid usage...1-3mAh (Batt Monitor Widget).
Nvm, ill get it
Well i had an hd2 and came from 1-3 mAh to 30-60 mAh on the s2 with the same apps installed. On the hd2 there was even more syncing enabled and wifi and gps always on. But everything else is better on the s2.
Sent from my GT-I9100
i use both at the moment. GS2 is faster with much nicer screen, youll probably miss sense until you get used to touchwiz or run a different launcher, (launcher pro has virtually the same widgets), but overall the GS2 is definitely worth it.
Dont expect the same battery life though, no matter what rom you put on the GS2 but as long as you get through the day and stick it on charge its no problem is it.
I've unplugged 2 and a half hours ago, its already on 48% lol. Don't flash a miui ROM.

Battery life tips?

My nexus 4 has dissapointing battery life, can someone please tell me any tips to increase the battery life? Obviously, lower the brightness, dont have too many apps running, try not to browse on chrome for too long, etc etc. Does anyone use any of the battery saving apps out there? Any tips would be appreciated. Thanks. Also, I dont understand why there are no mods/cases with an extended battery. Obviously the battery is not easily removed but I'd be fine with a thicker nexus4 if I could double my battery life.
root it and run custom ROMs and kernels, undervolt it and whatnot.
You can just buy a portable battery pack you know.. They aren't exactly expensive and serve the sane purpose as an extended battery case.
When people say that such device has got a disappointing battery life.. I wonder what it means. If a battery offers a sot of 8hrs..would this thing satisfy all?
I've used S3 which people say has got great battery life.. I got more or less the same battery life in s3 as i get from nexus 4...
Anyways..trying custom kernel and undervolting.it could give you better results..

Agreed. I have friends with s3s, one x and iphone5, and I honestly do not think the battery is bad at all. I'm pretty sure the battery lasts longer for me than for them. And I'm not one for "disabling features" either.
I'm running wifi/data both on and I never manually disable anything. My GPS is on 24/7, and I have all tracking options enabled (for google now). Using auto-brightness though. Still get 4h SOT and I stay 30+h normally without a charge. I do not game alot on my phone though!
I recently re-flashed google stock images (4.2.2) and franco's kernel. Also undervolted but if I dont get any "better" (in terms of heat) results I will definatly remove the undervolting.

This what you doing is putting up one heavy burden on the battery.Never disabling wifi/data & GPS on 24/7..Still getting 4Hrs sot out of 30hrs total battery life .If this is not great than i wonder what great would be..There is only Razor max which is gonna satisfy in terms of battery
PS->If you game a lot on Nexus 4,then the battery wont last longer
Guys u can try deep sleep battery saver app aka ds battery saver.....it puts your phone into deep sleep as soon as screen goes off.........getting 10+ hrs on single charge.......mhav a try

Have you tried Battery Guru? Developed by Qualcomm specifically for the Snapdragon S4 to improve battery life
You can try greenify, I believe the concept of this app is great and overnight on WiFi and the rest left on I loose only 2-3 percent. And wakelocks are pretty much gone.

Post your battery life here!

I've been noticing and reading many many posts regarding how bad or optimized our battery life is.
I had this phone little more than 24 hours now. And I feel like it hasn't fully when through the battery cycle. Thus killing my phone in less than 10 hours. This is with very light usage as well!
I've also turned off gps and wifi.
I have turned on stamina, along with various other battery saving features.
Now I am coming from galaxy s3, note 2, and iPhone 5. (my iPhone has this same issue and cleared when I've started using the phone and going through few charging cycles)
I just wanna make sure that our phone isn't plagued by the software, hence this phone is only available via t-mobile or Sony (unlocked as well).
Please post your battery life photos.
Including rooted or not.
Also post which rom / kernel you are using.
Mine: stock from t-mobile. And not rooted.

We already had/have a similar topic in the Q&A section, no need to open a new one.
I see a lot of wake events. Check what's keeping your phone from deepsleeping with wakelock detector.
Yup you have a lot of wake events, I had this problem too. I reseted, reflashed firmware multiple times and still experienced problems until I sent it to Sony and somehow now there is barely any awake entries at all. Only screen entries appear (blue line on screen) and no lines on awake.. I do still get *backup* wakelocks and some qcom_RX_wake lock though

i get about 20+ hours of stand by and around 3-4 hours of screen using it normaly not playing games
The phone was horrible initially and on 4.1.2 then after the 4.2.2 update it has been brilliant. It lasts me just over 24hrs on normal us with screen time between 5-6hrs. I'm very pleased as by 17h00 it is normally at around 55%. So it lasts me a full active day.

After 4 months my Xperia Z barely lasts a day with just 1,5h of screen on time. Sony said the battery is good. Restored different firmware, tried 4.1, 4.2, CM - nothing helps. I'm very unhappy...
The media server keep draining my battery...
But when I switch my sd card to a empty one or just remove it the media server nolonger drain my battery.
So I only keep a small amont of pic and musics in my sdcard and that makes the battery can last more the one day
the battery life was improved from 4.1 to 4.2 . That being said, the battery life is still much to be desired.

Tbh I was really worried about the battery life on the Z, I have had my phone nearly 24hours and I am not concerned by bad battery life so far. The battery seems very good actually, its no S4 but the S4 does have a bigger battery and uses a AMOLED screen. Iirc LCD/TFT use more battery or maybe I have got that wrong.

I'll assume you are not a heavy user of some sorts? The frequency of usage i mean.
I'm not sure about the screen part though but it does make sense if AMOLEDs screen uses less battery than LCD/TFT screens since they actually off the black pixels.

Actually, the processor is more powerful and has a better technology. That's why it will have MORE battery life.
The faster the processor goes to top speed, does what it needs to do, and go back to low, the less battery it uses. Also, the processor itself is more power saving, allowing more battery save usage.
Just bought one today and I love it. Display is better than the rviews said and its plenty quick. Have to say im very satisfied with this tablet

I think you're misinformed. It will have the same "size" battery, as in the overall capacity. I don't believe anyone has said it's the exact same battery. So the battery alone, at the same capacity, could have better performance(there's more to a battery than just the capacity). Additionally, as was already mentioned, the newer processor is even more efficient. Other random components in the device are probably newer parts(even if they have the same numeric rating specs) and are also probably even more energy efficient. The screen is the same resolution, but not the same screen. So it's probably even more energy efficient.
All of that said, I would expect similar if not increased battery life, on a tablet that most would agree is fairly good on battery life already(it's not "great" by any means, very few tablets reach that level today, but it's good enough for most to last a week or so with moderate use).
I don't think I'd buy a regular Tablet Z right now with the Z2 Tablet coming out within the next month or two, unless it was under $350USD(assuming the new 16Gb wifi model will sell for $500USD as the previous one did....here in the states).

Considering the price difference to the actual changes of the z2 Imo it didnt warrant spending almost double for the z2. I just bought the z1 for less than the $350 price tag and like you mentioned although id rather have the newer of the two it just didnt make sense paying an exra $200. This is an awesome tab nonetheless, quite overlooked and also unfairly reviewed Imo. My only gripe may be battery life

[Q] S4 or OPO - which one is preferable (battery life and performance)?

Hi everyone.
Thinking of getting either the international version of the S4 or the OnePlus One.
Will save some bucks if I get the S4.
With a new battery and MM custom ROM (are there stable ones?) I was thinking this might be a good device.
Or as owners would U say I should add a few $ and opt for the OPO?
Thanks a million!
don't know the battery size of oneplus but the s4 benefits from carrying a spare or using a high capacity battery. opo has a much better CPU. always go newer for me...

Thanks for that input. The OPO has a 3,000 mhA battery and since I am a light user, lasts me 2 days (running stock CM 13 MM).
I guess battery wise the S4 would be a downgrade then. Carrying an extra battery is not an option for me as I will lose it within a week
it's hard to judge but if you're getting two days usage out of 3000mAh then you should be OK with 2600mAh to get back to a charger again. roms with alucard's kernel can be underclocked and or undervolted as well as being run on a power saving profile. that said I'm sure opo has similar options available...
You can also get a 3000mAh battery for the S4.
That being said, it really depends on how high the price difference is.
I personally would go for the OPO, because of the better specs. But I dislike the fact that it has no card slot. This is pretty much a deal-breaker for me.
