W760 is a latest model as compared to K810i and has been rated better in terms of performance, design and features as compared to K810i. Both have exact similar features so i feel it to be good bargain provided the replacement phone is satisfactory in terms of its condition, performance and looks.
Otherwise its a fare deal. You can have a look at the comparison in the below link.

As for the battery, maybe the battery is weak that's why it drains fast. Maybe you should just go ahead and replace the battery. Make sure you charge the new battery before you start using it.

Take care.

Hi,the problem you are experiencing with your phone is as a result of a weak flex connector cable.it has to be replaced,here's a detailed solution on how to replace the cable. STEP 1. Tools required: Phillips screwdriver, plastic tool such as a guitar plectrum or credit card.

• Remove your back cover, battery, sim and memory card.

STEP 2. Run something like a credit card under the metal plate at the top of the phone. It is stuck down tight with double sided tape but it will come away with a little force.
STEP 3

• Starting near the top of the phone, run your credit card along the join of the front cover. When you have released the cover as much as shown below, slide the cover down to remove it (clips hold the cover on at the bottom which will be bent if you don't slide the cover off).

STEP 4 You should now have the front cover removed. Remove the small screw you can see. STEP 5

• With the slide open halfway, lift the up the part you've just removed the screw from to reveal three ribbon connectors. Each connector has a black latch which you need to flick over the release the ribbon
• STEP 6
• You now have the LCD screen removed. You don't need to go any further if you only want to replace the LCD.
• STEP 7
• Remove the speaker and connecting ribbon etc. It's just stuck down lightly. Remove the two screws you can see at the top of the phone.
• STEP 8
• You now need to lift the keypad up. It's stuck down lightly with double sided tape. Remove the two screws you can see.
• STEP 9
• Run your credit card around the join of the grey part of the phone to release a number of clips. Turn the phone over and release a few more clips in the battery compartment.
• STEP 10
• Your phone should now look like below. Two small bezels (shown in the picture) will pop off when you remove the back part of the phone. Now remove the two silver screws you can see.
• STEP 11
• You can now remove the battery compartment. A ribbon is stuck to the side of this and will peel away quite easily. Remove the two screws you can see.
• STEP 12
• The circuit board will now be loose but still connected by a ribbon. Again, flick the black latch over to release the ribbon.
• STEP 13
• Disassembly is complete. Reverse the whole procedure for reassembly.

I presume you mean for a phone?All questions need full 'make model (what it is)' as first 3 words please.The 'smart chip', normally referred to as a SIM Card comes from your cellphone service provider.
