Battery charging issue - Cant charge the phone. Wait till the battery completely drain-off only able to stand a chance to charge it. Its frustrating. I believe it is firmware problem.
SKU image issue - It come with CN / CUCC / TW / WW version. CN version is suck as it is not allowed google services to work with it. (I have done so many technical research to change the SKU from CN to WW.) How many of the users able to waste such time to do this?
Battery drains fast - it solve after i install the lastest firmware.
Other experience is good. Battery charging issue is frustrated.
To improve battery life 1) update the the latest firmware. 2) user auto-start manager to manager your start up tasks, the lesser the better. 3) Manage your app, with the latest firmware (Android version 5.0, software ino WW_18.104.22.168_2151104), you shall be able to disable a lot of bloatware including those preloaded by ASUS. 4) switch to super saver mode if you are not actively using wifi or daa. I am able to survive my phone for 1.5 day without charging (but of course I switch it off when I sleep and switch it on the next moring).
It Was Amazing among top 5 brands, I bought my Zenfone 2 ZE551ML (2.33GHz-4GB of RAM) one month ago. the phone is really amazing to use and very fast. the charging is really quick (less than 1h to full charge) but the battery life wasn't that good. If I wanted my phone to last the day I had to use the power saving mode. Feels Good.
Have been using my ZF2 ZE551ML since June till now.. and I'm really happy with the phone as it served my purpose very well for e-mailing, social media, reading news, games, downloading other apps, watching videos on YouTube and others, music and even took very nice photos in Beijing recently... its great, no regret buying it!
It's definitively good value for money..
Thank you ASUS..
I bought my Zenfone 2 ZE551ML (2.33GHz-4GB of RAM) 10 days ago. the phone is really amazing to use and very fast. the charging is really quick (less than 1h to full charge) but the battery life wasn't that good. If I wanted my phone to last the day I had to use the power saving mode. But after I uninstalled the Clean Master app provided by default, the battery life now is about 2 days with normal usage (WiFi, 3G, browsing, gaming and hours of calling), I think that the problem was in the Clean Master app that drain the battery. So for anyone who has problem with battery life, just remove that app and you will be happy.
hapontuKhen, 06 Dec 2015What I have is Asus Zenfone 2 ZE551ML with 16gb ROM and 4gb RAM.
Problems found are as follo... more1. Slow charging - you get fast charger with the 64/4 GB version only. You can get one separately for about 20~30$ on-line.
2. Every modern smartphone has some heating issues. You can't complain about that if you are a heavy user.
3. Gaming issue - try Settings-->Power management-->Power saver-->Performance mode.
I bought it yesterday.. seems okay to me except the battery drains way to faster then it should be.. and one thing, my one has Intel mrf 3560 and CPU 1.8GHz.it also has 4gb ram..l don't get it why gsm showing only ze551ml 2gb has those specs.
What I have is Asus Zenfone 2 ZE551ML with 16gb ROM and 4gb RAM.
Problems found are as follows.
1. Slow charging. (Fast battery charging: 60% in 40 min is not true in my case. It will surely takes 3 hours to full my battery from 5%)
2. Heating issue. (Special when cellular data is on, but not on wi-fi usage.)
3. Gaming issue. (This one is unconditional. Sometimes laggy, sometimes good or should I say this one is better than the other. Of course you can't play two or more games at a time, but you can do it just to test its game accuracy.)
I think that's all, those are the issues that I always experience. But above them all, this is still better than the other. Camera quality such as video recording, even selfies, voice recording, calls, texting, music player, themes, screen quality (brightness and contrast are average) and many more, those are good in this type of phone. I bought mine last June here in Philippines, until now my phone is good as a brand new. You must take care of what you have and be contented. :)
So many people complaining about this phone...I can't believe it. Mine is working flawlessly.
On screen time is 4-5 hours, most of it from gaming and the rest of it from browsing on Google Chrome or just using apps. I find that a decent on screen time, given that it's a 5.5 inch device and that I also have all the additional stuff activated (Flip Cover, Gestures,Motion, etc.). Plus, it comes with a fast charger so you can charge it back to 100% in like 1 hour and 30 minutes. Performance on normal mode is good, if you're on Performance Mode, it's perfect. The interface doesn't lag (using stock interface), the applications open fast and multitasking is a breeze (I tested the multitasking when I bought it, I usually don't leave my apps open, I use one at a time, maybe 2 or 3, for example when I need Google Chrome to find stuff). The 4GB of RAM does help a lot. Yeah, the system eats like 1/3 of it, but i think the interface wouldn't be as smooth if it was squeezed in less RAM. Call quality is good and camera quality is good as well for a normal user (we won't be using it to win photography contests,right?) The quality is a good one for regular pictures during day-time. Didn't try taking pictures during the night so I can't talk about it.
Gaming performance could be better, given what it packs inside, but it's still better than the performance on your average phone. It's just that some games aren't optimized for Intel processors. On the other hand, heavy games like GTA San Andreas, Asphalt 8, Modern Combat, Nova 3, Dungeon Hunter 5 have no problems running on it.
I bought my asus zenfone 2 last week. Yeah, it's really last week. At first, when i'm charging this phone, i thought it's not need too much time. But, actually 3 hours for full. So, i asked my friend who have this phone too, and she said that this phone is like that.
i'm still ok with that. But today, when i'm charging it again, it's already more than 5 hours. And it still 57%. I suprised with that. And when i check the time that i must need is 4 hours!:( what should i do? Please help me.
Btw sorry for my bad english, i'm not too good in english
omg :( I'm going to buy this cellphone (Zenfone 2 ZE551ML 32gb) tomorrow , hmmm now i read all the opinions :( cant buy
I brought dis phone and the only issue i found is heating but overall performance its ok better multitasking than s5 or note 4
The phone's hardware isn't the issue, Stock ROM is terrible.. flash it with CM12.. and it works like it should be.
im experiencing heating up issue with screen and back portion specially when charging or on mobile data
any remedy for this??
Do not buy ASUS ZenFone2, many many problem, lot and lot of problem, keep going down to the service centre, many intermittent problem cannot be solved, if you buy , I am 100% confident you will regret. . . You have be warn. . .
