Hi,

I recently had a factory reset, since my Xiaomi MI 3W was not responding! I use wifi most of the time, I have activated 3G data pack from Airtel (Service Provider), MIUI version - MIUI 6.3.9.0 (KXDMIBL) | Stable , the problem that am facing now is, when I select 3G only under Preferred Network Type (Mobile Networks), usually I had selected 3G only before factory reset & it was working fine, but now when I select 3G only there is no signal/service(emergency calls only), when I select 2G only or Prefer 3G, I get the service/signal, but I am unable to browse 3G data! :confused: If anyone has a solution, please let me know, since I have no clue of the customer support in India/Bangalore.

Thanks

Hi, I am having the exact same problem. And I'm also on airtel. When I insert this sim into anyother phone the 3g is working in that phone. I have been using this phone from past 1 year and i didn't have any probs until now. And the worst part is the customer service centre and the service provider haven't got a clue apart from throwing the problem on each other rather than finding a solution!!

[Xperia Z2 Tablet Q&A, Help & Troubleshooting] fearofbirds:
So first I want to acknowledge - I know that when you put a modified ROM on your tablet you apparently void the warranty. So with that knowledge in mind, i'm hoping people might have some thoughts on this.

I had my tablet with the Sony repairer previously because the screen cracked without any apparent cause. Sony fixed it under warranty (after some arguing).

Shortly after I got it back from the repairer, I attempted to install Cyanogenmod on the tablet and something went wrong, couldn't get past fastboot mode, and eventually the battery ran out and wouldn't recharge - even after being plugged in at the wall for 48 hours.

The repairer is now saying that Sony shouldn't pay for the repair because I voided the warranty. They want me to pay $300 to replace the Printed Circuit Board.

I can't imagine how installing different software would damage the circuit board. I think the tablet was damaged by the repairer internally when they fixed the tablet the first time around.

Does anyone have thoughts on this?

Hi all,

I have an issue when browsing using chrome while on mobile data.

For example: www.detik.com, below is the error message that I got:

The request is not understood.

Technical descriptions:

400 Bad Request - Check your spelling for the requested URL.

Another example is google.com (or any https link), it will simply give the error: This webpage is not available.

But those errors wont happen if I use wi-fi connection.

FYI, I have mobile data plan, I can WA, BBM, twitter, facebook, etc but not browsing in chrome.

Anyone experience the same issue?

Please help :)

Hey there!

I flashed the official Lollipop (Germany) rom that is posted in the Note 4 General forum two days ago without doing a factory reset. Right now, I am experiencing horrible battery life. GSAM reports that the phone radio is using 35% of the battery life. I also see the 4G icon blinking every few seconds, indicating that mobile data is being used. How can I solve this? My battery life was perfect before flashing Lollipop...:(

Many thanks in advance!

Maybe you should try a factory reset.

Although I updated without resetting and one of my friends did a full wipe before and after, and we both see a decrease in battery life. Nothing too horrible, but noticeable. So I think it's just Lollipop. After all, even the Nexus devices have been having battery issues with it.

See if a factory reset helps you, worth a shot.
[Galaxy Note 4 Q&A, Help & Troubleshooting] YoungStarDC:
Thanks for your advice. I will be sure to give it a shot. A decrease in battery life is pretty bad if you ask me. I thought Project Volta was supposed to improve battery life, not decrease it. And definitely not as much as is happening to me. By the way, the phone radio is still constantly active. I hope a fix will be out soon.

[Galaxy Note 4 Q&A, Help & Troubleshooting] iridaki:
I found WiFi to be the culprit for the rapid battery drain on Lollipop. Check out the following posts with my observations so far:

Below are screenshots showing battery behaviour with WiFi on (first 3 images) and with WiFi off.

It's important to point out that simply turning WiFi off doesn't appear to bring battery drain back to normal.

Turning WiFi off and rebooting fixes the issue, so long as you don't turn WiFi on again.

[Galaxy Note 4 Q&A, Help & Troubleshooting] bonerp:
I've started to have very poor battery life 7 days after installing the DBT lollipop. 60% after 4 hrs use today. It was good at first but has been getting worse by the day. Something was making the phone get hot just now so restarted and its cool shortly afterwards. However I cannot identfy what it was causing the overheating.

Is it worth trying to wipe the cache? I did a factory reset after the install as it was boot looping. I really do not want to reset it weekly! Google is crap at backing up all the apps - 160 out of 196 were reinstalled after the factory restart. Very poor.
[Galaxy Note 4 Q&A, Help & Troubleshooting] GeorgEveS:
Ok but we have a different problem here :) It's the Total Connection time of the apps that is 10 times the time the app was actually opened... See my screenshots to understand what I mean. And the problem I'm talking about - turning WiFi off and then rebooting doesn't fix it...

My Battery Life is really bad since Lollipop Roms.

I tried Wanam ROM and now Ketan LP ROM....

always have really bad battery life compared to KitKat 4.4.4

Here are my screenshots.

I also did a Battery Calibration but didnt helped.

Another BAD Side effect is that Antutu scores 43K on Lollipop... (on KK it was about 50k)

N910C

I will downgrade to KK 4.4 Wanam ROM with ADAM Kernel... that was realy awesome Battery Life....

I dont see any Reason staying on Lollipop
[Galaxy Note 4 Q&A, Help & Troubleshooting] xemtor:
After flashing original German 5.0.1 battery life was awful. I couldn't get a full day of light to normal use. Phone Radio was eating up battery life. I decided to use TWRP and install Alexndr ROM (clean install) forcing my local CSC (XEF).

*Great work, thanks Alexndr!*

After that, the phone radio was back to normal but now Google Play Services did the battery eating due to location services. So I set the Location Mode to Power Saving and deleted my Weather Widget which was the only one using location ... every 30 minutes ... (never look at it anyway). Now battery life looks pretty good.

I know cutting back on functionality isn't a real solution, but maybe my sharing this gives somebody some idea for a better solution...
[Galaxy Note 4 Q&A, Help & Troubleshooting] ManDone.vRs:
in 5.1 version of Lollipop will be fixed !
[Galaxy Note 4 Q&A, Help & Troubleshooting] bonerp:
^ interesting investigation. I've carried out similar checks and I still stand by the fact that wifi is an inconsistent culprit. This morning I left home so wifi disconnects, get to work and for some reason the battery is warming up and battery availability has plummeted. The highest % is showing as android system...?!

Regardless, I switch off the wifi toggle, within minutes its cooling down and back to normal battery usage - 3% in an hour with little use.

So far I've disabled FB as yesterday that was 15% usage for a short period when the battery started to plummet - even though I wasn't using it!

Something isn't right in this here lollipop. I am managing the system better than the system is at the moment!!!:mad:

***UPDATE***: I'm now 8 hours in with 75% remaining. Clearly it has something to do with WIFI and Facebook. Disable both and Lollipop is ok.
[Galaxy Note 4 Q&A, Help & Troubleshooting] motokenny:
I flashed back the official kitkat rom because of that. It appears (as i've noticed in multiple forums) that lollipop is preventing some devices from sleeping. Wifi, for example, is constantly causing wakelocks and therefore blocking the ability to deep sleep. (with more battery consumption as result)
[Galaxy Note 4 Q&A, Help & Troubleshooting] xemtor:
All above changes did get me some more battery live but "Google Play Services" still consume more than normal. I finished by installing Tasker and switching off the GPS. When using "GPS Apps" (Camera, Maps, Here) or connected to a power source I switch GPS back on (my Tasker task does). This workaround is perfect for me and I now have excellent battery life. Sure this is not suitable for those who use GPS constantly for Weather widgets for example.

UPDATE: Two days later for no reason battery drain was back again. This time the culprit seemed "Samsung Push Service" preventing the phone to go to deep sleep with a wake lock. I impatiently uninstalled it (I have a Titanium Backup just in case). Since then I do not have any issues with battery drain. I also have not encountered any issues because of the "Samsung Push Service" missing, but I do not use any of the S Apps neither.

So globally my battery saver actions currently are

Wifi Disabled during the day

GPS only enabled when connected to a power source or running a GPS App (Maps, Here, Chrome) [none of my widget are set up to use location services]

Samsung Push Service removed

BTW: I still use Alexndr's ROM with my countries CSC code (XEF)

I will share my experience with Lollypop as it has been somewhat of a change of heart with it... And might help or not

After my initial install I got about 4 hours use before it was dead... So reading threads I did a factory reset and clean install.. Got about 6 hours so as I'm sitting there downloading the kitkat rom to flash back I decided to have a mess about with it and installed Google now launcher... Had a look and went back to touchwiz stuck phone on charge and went bed the rom can change in the morning..

No time so took phone as it was, thought I had turned of gps and wifi as this was mentioned as well... Anyway 6 hours in and I noticed both wifi and gps was on but low and behold battery was on 70. % I checked and everything was running normal and the phone lasted all day... So decided to keep it and see what happens, I can report the phone with gps and wifi on is lasting 16 hours easy with normal use no battery only thing I'm getting is a Facebook problem were it sucks battery but I think this is down to notifications as it only seems to happen if I don't clear fb notifications.

So if someone else wants to try the Google now launcher see if it has any effect or I was just lucky that things changed and got better for me.

[Galaxy Note 4 Q&A, Help & Troubleshooting] h8Aramex:
By the way, try to update your Google Play Services to the latest version with an .apk install, and also clear your cache after that.

Google loves to mess up battery life on our devices, that's not Samsung specific.

"BatteryStats+" can also give a great insight, but sadly, only with root. (Don't trip KNOX.)
[Galaxy Note 4 Q&A, Help & Troubleshooting] robertbr108:
would it be ok to install this version - Google Play services 7.3.28 (1863718-446) - from here:

I have Lollipop 5.01 on my Note 4 N910C and google play services show version 7.0.99 (1809214-430).
[Galaxy Note 4 Q&A, Help & Troubleshooting] h8Aramex:
Yeah it's a legit site. But you can always run the .apk through the virustotal.com site before installing it.

After installing it, clear cache in recovery menu.

If it doesn't help, just try an older one (one version, then two)...

I know it's a hassle and a pain. This happened to me with the S3, Note2, G Pro 2, and others.

Google should really fix these stupid issues.

I am using the note 4 both for navigation and taking pictures, uploading them to Facebook etc. I took it of the charge at 7 am, using it to navigate to a city nearby for an hour and a half, took around 20 pictures (note is taking really great photos), at 10.30 I put them on Facebook using wireless at Starbucks, used it navigate around while walking, at 12 I was at under 50%. I am not sure if this is normal with this usage but this became my new normal since I have the phone and I have to take the battery pack with me always.

Do you keep Wi-Fi and location on all the time? I have seen post like yours before and no details... With Wi-Fi and location on the phone does not last one day on standby.
[Galaxy Note 4 Q&A, Help & Troubleshooting] h8Aramex:
Yes, both, for smart unlock.

I know my post was vague, and I didn't plan to write such.

The reason I wrote such a vague post is because I used the phone for a few days after getting it, since I have no case for it.*

But even after the initial install and 60% stock battery it kept going and going.

Then, after a full charge I worked setting up the phone, that means 4-5 hours SOT and still 30% battery life (now it's in the box.)

But don't take my word for it, I will charge it and post screenshots once my case arrives.

(It will arrive on Monday, Tuesday..around that.)

tl;dr: Exynos is just supposed to have a better battery life. Check for wakelocks, check for apps, services, etc.

Trust me, once she installs Viber, WhatsApp, Messenger, and the rest of the usual crapware, she will also get a terrible battery life. :)

* = Yes I absolutely hate scratches on the display/phone. When I noticed scratches on my S3 it annoyed the hell out of me.

Screen on time does not look bad but every time wireless is used I can see battery percentages going down in front of my eyes.
