That looks quite much yes :S i didnt logged or noticed any short battery life yet but just looked and still have 67% left 9,42 hours
after it was disconnected from the charger and with wifi turned on etc without having any battery saver installed yet,
have you checked that you dont have some heavy battery draining app? some apps will still drain battery in the bg when you dont use your device
there are quite some known (background) battery draining apps, the reason mentioning these are because they have more battery usage than is showed in an battery monitor app
Google Play (tries constantly to get your contact list and location)
Whatsapp, Skype, Wechat and other social media/chat apps (constant update traffic to and from their servers)
even when you minimised/closed these apps they still keep draining your battery invisibly
because they need and use a socket connection and rf hardware
here for the ones who like more useful tips/facts to improve battery time,
1. Connect your phone to the pc with an Usb cable, then you see the usb connection icon left on top, slide it down and select Charge only "Stop all Usb functions Lets you speed up Charging and decrease power consumption"
2. At settings goto Wifi and click on the menu button, then select Advanced, there deselect "Network Notification" and set Keep Wi-Fi on during sleep to "Only When Plugged In" (default is always)
also check if Wifi optimization is set to "minimize Battery Usage"
3. Download and open Mobileuncle, Choose Engineer Mode (MTK) then from the Telephony Tab scroll down and choose RAT Mode and the Sim and set prefered network type to "GSM" this can save upto 50% battery on Cellphone use) or
if you need/prefer 3G etc set to "GSM/WCDMA (WCDMA Prefered)" if the right network is choosen your drain will be less because it interacts more efficient and less with the right cell towers
and optionally you could disable some Band Modes wich you dont need,
also keep in mind that it helps your batterylife alot if you always put your phone on a place where the most signal is indicated! because when your phone receives a low gsm and/or wifi signal
it needs to send (re-sends) more packets from and to the tower also your phone will increase rf transmitting power resulting in a much faster discharging battery
4. Switch off the vibrate function
5. Switch off NFC when you dont need it
6. Ignore if your phone tells you that the battery is full since it is not accurate if the battery is not initialized, just wait 20 more minutes
7. Turn your phone off while charging (it charges better and faster) always use the stock charger and not an Usb cable
8. Remove the charge cable, Dont charge your mobile when you are using it! it will cause a faster discharge
9. Avoid fully discharging a li-ion battery! life is shortened every time you fully discharge them.
Instead, always charge them when the low battery indicator is popping up, using them longer is not doing any good (15-20%) 40% for spares.
10. New batteries start to perform better after you used (charged/discharged) them a few times

Yes if you are dissapointed and unhappy with this phone you are right to send it back but myself i am happy with it upto now
there is no doubt that there are better phones or cameras but do cost alot more ofcourse, as anyone knows for this low amount of money you can never expect best of the best and about specs are not always true so they must be verified this is not only the case with products from china but also european. it just happens more often with cheaper products,
you will get where you pay for with that in mind i was pleasantly suprised, the looks and all these features like Nfc, Bt4, also the camera looks nice altough i didnt tried or used it much yet, if need an professional camera dont use any phone.
as you can clearly see this value is in red color not for nothing in his du battery saver capture, normally it may never ever exceed 4.35v since it is the absolute maximum charge, so my guess is something is really wrong with his device or he tried to pre-charge it externally first.. really dont understand why people are so fixed to boost it to the maximum it is just not healty for the battery and will shorten lifetime or kill the battery
