[Android Q&A, Help & Troubleshooting] leomd333:
Right, this is s strange one. Over the past few years of installing ROM's I have noticed that if I say clean install a ROM, set it up, back it up using TWRP or CWM, fully wipe the device and restore that back-up, I get quite noticeably better battery vs staying on the first installation of the ROM. In case you don't get what I mean:

1) Clean install ROM and back-up that install, use original install for a few days, weeks, months whatever.

2) Wipe device and restore the previously created back-up.

3) Notice a large boost in battery.

This may seem insane, but I have noticed it on multiple occasions and I have no idea why it happens or how it makes any sense haha!

I never thought of it when using my G3, but with my Galaxy Note and One Plus One, it is a thing. I was only getting 3 odd hours of SOT on my OPO on COS12.1. Now after full wipe and restoring that exact same ROM (back-up made 3 days ago) I am at 2 odd hours SOT with 73% battery left...definitely a difference. I have dropped the brightness a bit vs before, but any other time I did this is made little to no change in battery.

Anyway, that is my odd theory, any input is welcome, call me insane, agree with me I don't know, but hey, it's worth a try!

[Sony Xperia C5 Ultra] zarerraldin:
I just got my C5 Ultra Dual 3 days ago... and the main disappointment of this phablet is the battery. Because the battery drains really fast, so i have to charge it twice a day. Actually it doesn't really matter, but this phone really have a super sloooow charging. When i checked the desktop charger, it only give 850 mAh output :rolleyes: (meanwhile other phones' official charger alreade give 1,5-2 A output).

I'm thinking of buying Sony EP881 Fast Charging (1,5A output), does it really charges C5 faster?

or do you know any other "faster" charger that compatible for our C5?

Thank you :D
[Sony Xperia C5 Ultra] cmmp:
Using an old note 3 2amp charger, makes it charge faster, but would also like to know re ep881
[Sony Xperia C5 Ultra] malih16:
I tried to charge using my old Zenfone 5 charger (1.35A) and it is indeed faster, my friend's Z1 also charges faster.

But when I use my iPad Air charger (2.4A) it's slow just like the desktop charger (850 mA).

So yeah because of this mixed results, I'd also like to know how fast it would charge with the EP881.
[Sony Xperia C5 Ultra] kanej2006:
I am using a Samsung high speed travel charger which gives out 2.1a. Very fast and charges my C5 Ultra in around 2 hours...
[Sony Xperia C5 Ultra] senthilrmohan:
guys,

i also bought a new sony c5 dual ultra phone couple of days before.

phone is dead now and unable to charge it from sony charger.i tried with computer usb port also.

please suggest me something.
[Sony Xperia C5 Ultra] kanej2006:
Return it for repairs or replacement...
[Sony Xperia C5 Ultra] senthilrmohan:
dear

i bought it in dubai airport during my transit.

is it possible to check with them.
[Sony Xperia C5 Ultra] kanej2006:
Oh dear. There are two options.

1 - Try returning the phone to the nearest Sony dealer. Show the original receipt which will show the device is new and still under warranty. Hopefully they can resolve the issue.

2 - Sony may ask you to return it to the shop where it was bought. Unfortunately you may have to return it to the shop you bought it from in Dubai Airport. They will most likely send the unit off to Sony for repair or replacement.

That said, try option 1, much more convenient. Hopefully they can solve your problem without having to mess about returning it to the original shop which happens to be in another country! Otherwise you may even have to ship the item along with the receipt to the shop. Once they receive the unit they will advise you on what they will do and how long it will take for it to be fixed/replaced. Once that has been completed, they will need to ship it back to you.

Either way, good luck and let us know what happens!

Bought this phone when I was in Thailand when I killed my Nexus 6 by walking into the ocean while it was in my pocket..lol. Anyways, the phone is slow at charging, not like my Nexus 6 which takes only 15 mins to charge fully. I switched to the Motorola Nexus 6's turbo charger and my C5 is charging A LOT faster. Standard charging is 5V [MENTION=1247388]1.6[/MENTION]A, Turbo 1 is 9V @ 1.6A, and Turbo 2 is 12V @ 1.2A. Not sure if the C5 is a Turbo charging enabled device but it's definitely charging way faster than the stock charger.
[Sony Xperia C5 Ultra] jslim38:
I've used my old Samsung charger that came with my old s4 and the charger puts out 5.0v at 2amps. And I used it on the original z ultra and I tested it on my new c ultra and it works great however I have realized that these particular phablets really don't charge that fast and from my experience they never have but they are at best average when it comes to charging. Oh by the way I also have the original Sony charger u s version and I see vary little differents in the amount of time it takes to charge
[Sony Xperia C5 Ultra] Bavz08:
But will it damage the battery or affect the battery life if we use a 2A-5V charger??
[Sony Xperia C5 Ultra] kanej2006:
Not at all...
[Sony Xperia C5 Ultra] Seshcena:
Are u sure charger giving 1.5-2A output if used with c5 ultra will not harm the phone
[Sony Xperia C5 Ultra] mingkee:
Not at all.

I use various chargers (Anker, Samsung, LG, Apple) and all of them work better than original, but you should leave the phone idle when charging.

---------- Post added at 01:29 AM ---------- Previous post was at 01:26 AM ----------

The phone charges on maximum ampere it can take (~2A) no matter the charger is 100A as long as the output stays 5V.
[Sony Xperia C5 Ultra] Seshcena:
Yes but what will happen if we use the phone while charging. Please tell the consequences
[Sony Xperia C5 Ultra] mingkee:
I played Candy Crush Saga when charging. The phone can be hot but it doesn't make your hands uncomfortable.
[Sony Xperia C5 Ultra] Seshcena:
What happens if we change charger means sometimes use 2A charger, sometimes 1A or 1.5A
[Sony Xperia C5 Ultra] jetstreamblue:
The amp rating on chargers are the max it can output. It doesn't mean it has to output that. Your phone's charge circuitry will control the current it actually draws. So there is absolutely no danger to use a higher amperage charger with your phone. However, I found that no matter what charger I use, including those rated up to 2.4A, the C5 is very slow to charge. It takes a lot longer to charge compared to any other phone I've had in the past. I'm going to get a current monitoring device to check actual current draw.
[Sony Xperia C5 Ultra] mingkee:
A side note: avoid REV (sold on BestBuy) external battery because the phone refuses to charge while Asus 10050mAh and TSST 5Ah and 10Ah external battery charge fine.
[Sony Xperia C5 Ultra] kanej2006:
In my case, if the battery is 5% or less, it'll take around 3 1/2 hours to charge. However, should the battery be 25-30% it'll just take around 2 hours to fully charge...
[Galaxy S III Q&A, Help & Troubleshooting] idowolf:
I have TWRP v. 2.8.6.1 installed on my i9300. Before installing a custom ROM I've backed up everything and got a folder called "2015-08-15--01-41-03_XXX" (snipped the last part).

For some reason the phone is unable to recognize a USB stick connected through OTG, so I'm restoring it from my external SD card. I can see all the files if I choose "Install" or go to the File Manager through the advanced settings of TWRP, but the MicroSD card (yes I made sure I've switched to the external SD card) appears completely empty when choosing "Restore".

The folder "2015-08-15..." sits at the root of the external SD card.

EDIT:

Solved by restoring original file structure for the backup. Didn't realize TWRP was so picky about it.

I went back to stock out of the box lg kitkat rom from cloudy rom by flashing KDZ.In my update app there is no ota software update showing,it is only showing as usual Lg app updates.I flashed the KDZ numerous times but not any outcome..Is my ota blocked due to flashing recovery or rooting?Do they do that?Did they block my imei?:eek:
[G3 Q&A, Help & Troubleshooting] redduc900:
Sometimes it takes awhile (may be upwards of two weeks or longer) before an OTA update shows up as available after flashing back to stock. And it wouldn't be blocked because you previously rooted and installed TWRP. Just make sure you don't do either if you plan on taking the OTA. If you had instead used LG PC Suite to go back to stock, you would have ended up w/ the latest software available for your phone, and wouldn't have to worry about taking an OTA update.

I've been trying to update my MDA to WM6 here for about the last hour. I read the thread about loading the 2.26 ROM and then it just says to update with whatever WM6 ROM you want. So I have the rom from the T-mobile Dash ver 1.22.531.4_4.1.13.34_02.79.90 but it fails. I connect the MDA, then make sure it has the ActiveSync connection. It then goes through reading the current rom and then when it gets to the loading screen where its the 3 colors on the MDA and the 0% waiting screen it then says there is no connection.

What's up with this?

[Zuk Z1 Q&A, Help & Troubleshooting] gerardgerard:
Hi,

My ZUK Z1 european version has just arrived and I am noticing that it cannot take the 5Hz wifi when there is some distance in between. If it does it, it disconnects in seconds. It does connect to the 2.4Hz g without too many problems (some times even not this one). If I put only 5Hz networks, the same happens. Sometimes it doesn't see the signal at all.

This doesn't happen when I am next to the router. So, since the 5Hz deteriorates more with distance (AFAIK) what I'm describing shouldn't be surprising. My doubts are because with the nexus 4 (Android, not cyanogen) it grabs the 5Hz without any problem at exactly the same long distance (2 thin walls, few furniture in between), and I find very unlikely that the wifi chip of the nexus 4 is superior than the one of the zuk z1.

UPDATE:

It is very strange. With the ZUK, in front of the router I get 110 Mbps (5Hz, n-only), when I move to the room in question I get 3-4 Mbps only, so about to be disconnected.

With the nexus 4 (same 5Hz connection obviously), I get 50 Mbps when I am in front of the router AND when I am in the problematic room. How is that possible?

If I test connecting to the 2.4Hz (b,g,n), the nexus 4 gives the same 40-50 Mbps no matter the distance. I have to go to a very "protected" room to see a drop to ~15 Mbps, again showing no difference between the two bands.

If I test with the zuk, it gives 20 Mbps, if I move to the very "protected" room, I see a drop down to 0.3 Mbps

So, it is like the wifi is much better if you're in front of the router, otherwise is significantly worse? Is that feasible? Can it be a software problem?
[Zuk Z1 Q&A, Help & Troubleshooting] Rom91:
Hello! first of all excuse my bad english

I received today me ZUK 1 and im having the same trouble, its impossible to use wifi without problems when you are in a different room from router, and especially when you put the smartphone in horizontal position ,grab it with two hands and cover the superior part with your hand, when i do this i simply lost the connection even if im in front of router. I come from HTCmania, a spanish forum of smartphone and we are few people with the same problem and is very frustating that there is no solution and noboy in Lenovo or ZUK says nothing about this trouble.
[Zuk Z1 Q&A, Help & Troubleshooting] Africa2k2:
Me too. Wifi is very very very bad if you hand is in the top (camera zone). Horizontal, vertical, it does not matter if you cover the area with his hand, zasss wifi dies.

Sorry my very bad english.
[Zuk Z1 Q&A, Help & Troubleshooting] dp12776:
Same problem here

I have the same problem as described. I have not noticed if my hand position affects it. My OnePlus one and my Sony Xperia Z1 compact both manage to hold on to the wifi in my bedroom albeit less than full signal. The Zuk z1 just keeps dropping off and sometimes doesn't find the wifi.

Have anyone contacted Zuk about this? Mine was bought through Spanish eBay but seems to have been sent to Spain from Germany.

Following the thread for a solution as this problem is a definite dealbreaker.

Daniel
[Zuk Z1 Q&A, Help & Troubleshooting] gerardgerard:
Uau, I've just tested it and while it is unrelated to the problem that I say (this is, the ZUK receives the 5Hz band very bad it seems) it is completely true. While doing a wifi test (Wi-Fi Deadspot app), connected to the 2.4Hz, from 55 Mbps if I put the hand over the top part of the mobile it drops to 30, if I put the hand in the middle part of the back zone it drops to <5Mbps!!

*Having it over a table doesn't make a difference for me.

UPDATE: The measurements from this app seem very variable, based on other comments it doesn't seem to be related to the software but to the ZUK. Now the 5Hz band gives excellent results from the room where before it couldn't even see the wifi.

So it does seem capable, but VERY unstable I guess. Is this hope for waiting a software-based solution? Or we should mark this phone as a wifi-less phone ...

(damn ~_~ they sure knew about this from the units sold in China)
[Zuk Z1 Q&A, Help & Troubleshooting] dp12776:
2,4 ghz

Just checked and it turns out that my wifi is on 2,4 ghz. So I guess the conclusion is that the problem is unrelated to the frequency.
[Zuk Z1 Q&A, Help & Troubleshooting] gerardgerard:
There are two problems:

Problem 1- Wifi drops when your hand is on the top of your phone, irrespective of the frequency

Problem 2- Wifi in the 5Hz is very unstable and/or much worse when compared with a nexus 4 phone (relevant provided it is an old phone), related to the frequency (or it seems so at least)
[Zuk Z1 Q&A, Help & Troubleshooting] I-Immortal:
I didn't noticed anything before i read this and tried to put my hand on the upper part of the phone : my WiFi connection instantly shut down even if I had 3bars over 4... So yeah there's a real issue with the WiFi antenna here :S (first real drawback I have with this device...)

Apart from that, I owned a Nexus 4 too just before this device and I personally have a better WiFi reception on my Zuk Z1 (one more bar for both 2.4 and 5Ghz bands) :)
[Zuk Z1 Q&A, Help & Troubleshooting] othe01:
Does the same happen with ZUI os?
[Zuk Z1 Q&A, Help & Troubleshooting] xavieramoros:
I also have a Wifi problem with the international version of Zuk Z1.

Testing the Wifi with the App "Wifi DeadSpot" in both the Zuk and a Oneplus 1, the results are:

2m far from the router:

OnePlus1: 38Mbps (GOOD)

Zuk Z1: 9Mbps (AVERAGE)

10m far from the router:

OnePlus1: 22Mbps (GOOD)

Zuk Z1: 0.45Mbps (POOR)

In both cases the phone is in vertical and without touching it (holding it near the camera apparently really makes Wifi coverage worst)

If the Zuk is in horizontal position, the Wifi signals is also worst: 0,5-1 Mbps at a 2m distance.

I tried resetting the Zuk to factory settings and the results are the same, so I don't think it's a software issue. Could be a manufacturing defect or just a cheap wifi chip?

But not sure if its a software or hardware issue, i guess hw.
[Zuk Z1 Q&A, Help & Troubleshooting] tuatara42:
It's pretty random...

If i have the phone 3-4m from 2.4ghz router through a wall:

Keeping the Z1 in the same position, without touching it, WiFi reception varies from 2-4Mbps to 40Mbps (from test to test in Wi-Fi deadspot app). Can't predict when I get which speed. Mostly it's very low, though.

Disconnecting and reconnecting sometimes helps but mostly it doesn't. My old Huawei Y300 has a solid ~18Mbps when tested at the same spot.

Then again also the phone reception randomly drops from 3 bars to 1 to just go back up to 3 all within 1-2 seconds. (which might be unrelated but coincided with having higher Wi-Fi speeds)

Here's hoping for a software bug....

Cheers.

---------- Post added at 02:57 AM ---------- Previous post was at 02:37 AM ----------

There is one thing that is rather consistent though:

Whenever the display turns off during the Deadspot test, WiFi drops e.g. from 40Mbps to ~8Mbps. I first observed it by chance and then switched off the display on purpose several times while the app was running...

In the WiFi settings it's set to always keep on, so that shouldn't be the issue...
[Zuk Z1 Q&A, Help & Troubleshooting] othe01:
[MENTION=7006460]tuatara42[/MENTION]

I think i noticed sth similar, i had map downloads for navigation, around 2gb of data, it was half done in a few minutes but when it gone into standby mode and i woke it up 10 minutes later it barely progressed, so that means the wifi must have been slower.

That gets me a bit of hope that it´s "just a software problem".
[Zuk Z1 Q&A, Help & Troubleshooting] tuatara42:
I just tested the speed right next to the router:
