[Galaxy Note II Q&A, Help & Troubleshooting] @rbiter:
Well, previously everybody was thinking and seeing that LTE used more power and basically it did. Most of that was attributed to lte using a second board for the radio. As second gen lte radios have been integrated onto soc's it has been noted that lte can be more efficient if utilized properly because with lte's low latency and quick bursts of speed the phone can race to idle quicker. I am sure this is a very effective for people who use sync services a lot. If used properly, I am sure the phone can poll for data in quick bursts and can definitely help battery life. This is not always the case between OEM'S being lazy and sloppy and depending on what and how often the phone needs to poll for data. I would also think if lte has bad reception it can have a worse effect than hspa would. I almost got a carrier version of gnote2 to have lte because I want to test it so bad but I hate my carrier enough as is and I hate bloatware with a passion.

First,thank u "@rbiter" because of ur opinion,but my intent was that,considering by my carrier 3G speed(3.5G up to 7.2 MB but generally is less than 1.5 MB) Galaxy Note II LTE version uses more battery life than Galaxy Note II 3G?and is it a huge differnce?or is it sustainable?
[Galaxy Note II Q&A, Help & Troubleshooting] trioxyn:
4g speed is worth the battery life i would say..i am a 4g user..:)
[Galaxy Note II Q&A, Help & Troubleshooting] @rbiter:
From what I've read they are comparable. But at the same time I've noticed some people getting up to 20% less battery than the international version. A lot of factors go into that like usage and reception. If you really want lte, I would say get it, that is if you really need more than 1.5mb/s more often than not. I turned it down because I am fortunate enough to get up to 5mb/s in ideal situations and 1-3mb/s in less than ideal situations and plenty of WiFi in between.

I wanna buy Galaxy note II LTE international version!!So what is your suggestion?:o

here carriers want to provide LTE this year,but if they don't launch it at right calender,and Galaxy note II LTE drain more power in contrast of 3G version,it will be lose-lose game!!
[Galaxy Note II Q&A, Help & Troubleshooting] @rbiter:
Make sure the lte bands are compatible and that you have coverage. If you don't have coverage I would just get the n7100. BTW, even though I think Nokia and Motorola by far still make the best phones as far as reception is concerned, Samsung should get an honorable mention for being very battery friendly when signal is poor. Nokia too. Motorola is iffy when it comes to poor signal. And not to mention, the galaxy note 2 gets very good reception for a Samsung phone and by far has the best WiFi reception of any phone I have ever had. Even better than my atrix.

[Galaxy Note II Q&A, Help & Troubleshooting] seyedshahaboddin:
But I confused again,let ask in another way,image that I have 3G network,I have to choose gnote II n7100 or n7105, in same setting and usage n7105(operated on 3G mode) drain power as much as n7100?or more,how much?
[Galaxy Note II Q&A, Help & Troubleshooting] @rbiter:
if you buy an 7105 and don't use lte at all, it will probably get a little less battery like i mentioned before. otoh though, it has dc-hspa so it would depend if you get the same as n7100 on your coverage and speeds. anyways, at most you will probably see a 20% loss of what you would see with a 7100. at most. anyways, quit asking for my approval. if you can get an unlocked n7105 and don't mind a small POTENTIAL loss, you should be good to go.
[Galaxy Note II Q&A, Help & Troubleshooting] seyedshahaboddin:
A small potential lose how many hours is? normally I use Google dictionary,YouTube,what's up,viber and Facebook.8 hours per day,3 by wifi and 5 by mobile network,my what's up,viber and Facebook are sync on,N7105(International version) is ok?
[Galaxy Note II Q&A, Help & Troubleshooting] @rbiter:
many are still getting well over 7 hours screen time over a whole day. some with more, if wifi is used.
[Galaxy Note II Q&A, Help & Troubleshooting] ronzza:
Im using n7105 and battery will last a full day with 4-5 hrs screen on.

I do enjoy the dc-hspa speed since im always out and about.

I use EE in uk on non 4g plan
[Galaxy Note II Q&A, Help & Troubleshooting] gasolin:
If your not planing on getting a 4g plan with more then 21 Mbps in download don't buy a 4g even if the price is the same, because you only get higher speeds then 21 mbps (max download of the 3g version) a few places, and even with 3g i only had 10-16 mbps as max on my sgs 3, my 3g plan was 32/5 (i also have a note 2 but only with a std fast 3g net,plan). The battery time should also be alot better on the 3g model

For facebook,twitter,youtube and mabye if you have an app for the busses and trains when they drive and if you only google something a few times every week, 3g is ok as long as the speed is stabel
[Galaxy Note II Q&A, Help & Troubleshooting] sonatamartica:
Ordered the LTE

Well i read this topic in its entirety and still seem pleased with my decision. I just ordered the GN2 LTE for $539, and by the way people are carrying on it seems that with or without 4G, the battery will last around a day with normal use and a bit of gaming. I'm used to charging my phone every night (previous phone was a Galaxy Tab 7.0 Plus). Also I agree with the guy who created the topic. not everyone is rich, $700 odd dollars is expensive for some people. I bought 4G to futureproof as well, i dont see how the technology will be surpluss or redundant in the next rear or so, i know alot of people still using droids that are only almost 1ghz. some of my friends have phones like 2-5 years old. another guy i know swaps phones like 7 times a year. I know this is a forum for tech savy people, but often others find it in google and sign up to ask things such as this. Its unfair to generalise.

As a side (galaxy) note :p

even if you have the phone already, this is one amazing review, not like the average youtube look at.

this guy should be making television shows!

There's no way you got 9-10 hours of screentime. Unless you're disabling EVERYTHING. I'm at 33% on my Note II and I only have 2 hours and 55 minutes of screentime.
[Galaxy Note II Q&A, Help & Troubleshooting] aloush5592:
Lawtq is right.....i too get 10-12 hours screen on time...but hey...thats the fact:

1) undervolt every cpu freq too -100mV

2) the gpu min freq. 54mhz and max freq. 350 mhz ...undervolt every gpu freq step to - 125mV

3. I am just using 1 core everytime..the other 3 are offline...beacause i use my phone just for social chatting ( whats app e.t.c.) and music.

4.and i am using perseus kernel a34.2 with latest official miui v4 3.22.2 ...based on sammy tw.

Then either you have wakelocks everything's turned on and running , my first day with my n7100 i had 9hours screen on time first day with this 4g version 7hours screen on time
[Galaxy Note II Q&A, Help & Troubleshooting] Dr. Hax:
Definitely no wake locks. My Note II does deep sleep just fine. The only thing is the LTE signal at my house is pretty poor. But with HSPA+ I can get as much as 5 hours. I used to be able to get 6 hours but no ROM seems to allow that anymore. I also know that nothing is causing wakeocks cause I have very few apps installed. I set gmail to run as normally, haven't tweaked that because I know push sync doesn't really tax the battery. Weather syncs once per hour. Gallery syncs facebook once per day. I can't set my GPU below 160Hz (or whatever the step is above 100MHz because then I notice smthe keyboard lag when typing. But I doubt that really makes q big difference for battery life anyway.

Right now I'm at 2 hours and 7 minutes of screentime on the stock ROM with 44% battery. Most of the day I was at work and had a good HSPA+ signal with LTE disabled. Ever since I got home I enabled LTE. It's been off the charger for 20 hours. Oh, and as of now, I'm also using the stock kernel. I don't know what to do. Maybe it's possible I have a bad battery but that's pretty rare..

---------- Post added at 03:16 AM ---------- Previous post was at 03:11 AM ----------

And the reason I'm on the stock ROM is because I was getting pretty terrible battery life on Cleanrom ACE, especially after 4.5. I'm trying to eliminate variables but I don't really know what to do anymore. I'm almost about ready to call up T-Mobile for a warranty replacement because I'm not even able to get 5 hours of screen on time anymore.
[Galaxy Note II Q&A, Help & Troubleshooting] foxmeister:
Prior to 4.1.2, I could easily get 9-10 hours screen on time on my Note 2 without doing *anything* to maximise battery life (I.e. nothing disabled).

Now I'm on 4.1.2, my battery life has dropped and is closer to 7-8 hours screen on. I'm hoping that a later ROM will improve battery life again.

YMMV due to your usage patterns - intensive gaming will drain the battery far faster than my usage, which is mostly videos, web browsing, and forums.

Dave

using the ADFU mode, through the recovery menu:

1) erase user data partition

2) enter adfu

3) upgrade firmware from sdcard

4) exit menu

everything went fine but now the touch is not working.

Im trying to use now livesuit to flash another available rom but the software cant seem to find the tablet. I used the following methods:

1. plug usb with volume+ and power buttons

2. plug usb with volume- and power buttons

3. plug usb with menu and power buttons

4. plug usb with volume+ and reset buttons

5. etc

And nothing seems to work. I used version 1.05, 1.07 and 1.09 of livesuit.

Please help? I really need it.

Thanks in advance.

hi i got same tablet as well with the same problem. i flashed mine and now touch screen don't work and I cant use the biult in recovery (menu vol+ and power). also memory card slot dosen't work. the buttons don't do what they are suppose to like vol+ I press it and its menu button i changed what it dose by editing a file so its volume. but i still cant access recovery menu on start up, the only way I can see fixing it is if i can fix the recovery menu so i can get it to show up or wait for someone to figure out how to install clockworkmod recovery on the same tablet making a copy of there firmware then using that.

Hello, i have this GL5201 or GS701B (the same) chinese tablet and i try to replace the firmware, but i'm really a noob in this matters, so, can you help me kinda step by step to put the firmware inside the damn thing, please, i already download all the things in the link you have posted, the one with the PC201231-Q8-0329 camera zip thing is like not ready to use and put in a micro sd card or really dont know, thats why i'm asking for help, please, please, please.

By the way, i have already downloaded, unziped and installed in to my tablet the TF20121031-q8-0329 camera zip and the 20121031-q8-0329 camera zip and both of them is not getting the touchscreen to work, thanks a lot for your patience and time.

Hello, let me tell you the full story, happen that the tablet was working fine, but suddenly starts to send messages like, "unfortunately androi.acore.something has stopped" and then "camera" and "facebook", and every app i had started, but touchscreen was working perfect even with the messages going on, that's when i decided to flash the tablet thanks to a some recommendation on the internet, i had no idea in what i was getting in to, so i put the thing on the micro sd and did the steps to flash the tablet, and everything looked good until i tried to use the touchscreen, wasn't working, thats why i believe is not a hardware issue, anyway, if you have any solution for me, i'll love you for the rest of my life (lol), thanks in advance.
[Android Q&A, Help & Troubleshooting] alejob54:
I had the same problem(Solved)

I bought a chinese cheap tablet.

Model gs701b,

Android version: 4.0.3

Kernel 3.0.8 wineulo@Monia-Server #15

And the next day that crap stop working. There was a error message. "unfortunately the process android.process.acore has stopped" and so on with the applications. Some days worked, some days didn't, even the keyboard stopped working. First i did, was to reset factory data on settings. it didn't work. then turn it on with the power button + Vol+. and select the 1 option. Erase user data. Didn't work as i expected, the problem went on. So i started to read on internet and after searching for a week i followed the instructions provided here

/* I can not place the link here because it says im new, so search in youtube : gs701b " and the video with the name "Tablet PC Q8, gs701b, MIPS, ATM 7013, not Allwinner A13" thats the one */

I downloaded that file and did what he said.

Some people says that method does not work and their touch screens got locked, as you can read on the video comments. I think its because their models weren't the same.

So i did it with my gs701b and everything went perfectly. I just put that file(extracted) on the recently formated MicroSD, rebooted it with power button and vol+ pressed, selected option 3: upgrade firmware from SD and it took a few minutes, no longer than 5. Now apps work fine and the touch screen didnt screw up. I hope it helps someone as this forum and the video did it.

Sorry about my english. I speak spanish.

PS: after i did it, the android version is still the same. 4.0.3

Can i downgrade it to android 2.3 ? i think it would become faster. Thanks

---------- Post added at 09:41 AM ---------- Previous post was at 09:37 AM ----------

hi

Hi, i also did the steps from there, and the touchscreen does not work, I don't know if there is 2 kinds of gs701b, to be precise, there is 2 different models of gs701b, the one with the home button and the other without it, so i don't really know if I can use that stuff on both, the one is not working is the one with the home button on it, I have both because I resell those, I really need the stuff for warranty purposes, really appreciate your comment and thanks, by the way, I'm a spanish speaker too, but we can't write in spanish here.

if after the hardreset the touchsreen is not working and the reflash is the firmware has the same effect then its definitely a hardware issue with the screen, its a shame they havent released any other firmware updates, anyway for warranty purposes reflash the firmware, and take bak to vendor is you are not having much joy.

Hi.

Same problem here: after installing TF-20121031-Q8-0329camera.zip from SD, my screed died. Before that, all was working fine. The partially good thing is that I've got another full working tablet, same model.

For the record, I'm a complete noob in Android stuff, but willing to try. :) My ideea was to somehow dump the working ROM from the tablet that is working and restore it on the one with the dead digitizer.

Is it possible to do such a thing? Also, I've got a zip with three files: icecream_gl5201_q8_rgb.fw, misc.img and system.img. Are they useful to something?

Thanks!
[Android Q&A, Help & Troubleshooting] brynthomas:
the zip file you got is for flashing by pc. I tried opening the .img files on computer I was only able to open misc.img. in it there's a folder called modules inside that it's got .ko files. one of them is called enteradfu.ko. I don't know what you do with these files or where you put them on tablet. another thing I noticed is when I have used a program or by using adb to reboot to recovery or bootloader the tablet just switchs off. I think something not right. I know there's ways of installing clockworkmod recovery by using a program on the tablet or by using adb. either we need to work out how to install that recovery image or using similar methods to reinstall the original recovery image for tablet.
[Android Q&A, Help & Troubleshooting] MackTK:

[Android Q&A, Help & Troubleshooting] brynthomas:
you could ask someone on here who can post links to post your link for you. if people are looking for driver for there tablet doing a search for 'gl5201-adbdriver.zip' will help them. you would need to uninstall the drivers you got then use the driver you downloaded. you may need to copy a file under your user account . here's the instruction I got for this driver

1) Enable Developer Mode in the tablet

2) Connect the tablet to PC and don't let it search drivers on windows update (it'll fail the search but don't worry)

3) Go to the devices list and choose to update/install the correct drivers

4) Extract the content of zip attachment on the Desktop and choose that folder for correct installation of the driver (you'll see "Android ADB Composite Interface"

5) Replace the default adb_usb.ini in your "%USERPROFILE%\.android" folder with the one inside the .android folder in the zip attachment link

6) The installation is now complete, now if you write "adb devices" you can see "Actions semi. device" and you can dmesg and logcat it directly from usb.

I would warn anyone that if you messed your tablet and you have no way to access the recovery menu anymore that you should be careful what you change because if you make a change that stops it starting up you can't fix it. I have opened mine main reason is when I first put memory card in it didn't slide into memory card slot instead it got stuck in case. I noticed there isn't any 4 large solder points next to each other but theres loads of unused tiny solder points on board so you could connect a serial cable to board so you can communicated directly to board by connecting it to computer. if this was a option you could tell the tablet to install firmware off sd. a usb to serial is about £2.but it would be impossible to tell what each empty solder point dose.

my tablet is not working at all it goes to loadup screen then freezes. before that it couldn't read sd or load into recovery. its bricked now. I have emailed the seller of my tablet asked them if they got any externally broke tablets where it works but might have a cracked screen or broken case. I have also emailed some of Chinese company's who sell atm7013 tablets asked them if they got any cosmeticly damage tablets for sale or if they would sell me a circuit board for one. worse case I can buy a new one for £42.99 on eBay. and use the tablet I got for spare parts.
